## Arbitrary precision arithmetic

Although this is already supported in an easy to use way by the Wren-big module, there are some RC tasks which that module (written entirely in Wren) struggles to complete in an acceptable time or to a satisfactory standard.

I have therefore written a Wren wrapper for the C library, GMP, to deal with such cases. This supports arithmetic not just on integers and rational numbers (as Wren-big does) but also on floating point numbers of arbitrary size. Most of GMP's functions (around 190) have been wrapped though some - notably those concerned with input/output and random numbers - have been excluded as I didn't think they would be very useful from Wren's perspective. I have also included some additional 'convenience' methods which can be coded in a few lines using the GMP functions as well as some prime factorization routines.

GMP is not an ideal fit for an object oriented language such as Wren because arithmetic operations mutate the object itself rather than producing a new object each time as 'normal' arithmetic (and Wren-big) do. However, this constant recycling of memory means that fewer variables and less garbage collection is required for a typical application and so there's an inevitable trade-off here between maximizing efficiency/performance and easy of use. In an attempt to retain as much of the latter as possible:

1. I have included versions of the main functions which operate on and always return a reference to the current object which reduces verbosity and enables method chaining. These methods also sense the type of the argument eliminating the need to have separate versions for GMP types and unsigned integers.

2. The three classes: Mpz, Mpq and Mpf all inherit from the Comparable trait which mean that the normal ordering operators (<, <=, ==, !=, >=, >) can be used for comparisons.

3. I have also included operator overloading for the basic arithmetic operations with the difference that these always produce a new object rather than mutating the current one. Consequently, these should be used sparingly in scripts which need to maximize performance but can be used more freely in other scripts to provide a more 'natural' programming experience.

4. Memory is managed automatically by Wren which calls an object's finalizer just before it is about to be garbage collected. The finalizer in turn calls the appropriate GMP 'clear' function to ensure that memory allocated to the object is fully released. So there is no need for the user to call this function directly and, to avoid 'double clear' scenarios, it is not exposed by Wren at all. If you want to reduce memory usage prior to garbage collection, then the object's 'reset' method can be called instead.

5. The wrapper also ensures that Mpf objects are always canonicalized so there is no need for the user to worry about this particular aspect.

### MPF or MPFR?

I did wonder about using MPFR rather than MPF for floating-point support. MPFR is undoubtedly better not just from a technical perspective but also because it supports many more functions (notably the transcendental functions) than MPF does and even the GMP folks themselves recommend that it should be considered for new projects.

However, it's also far more complicated to wrap and doesn't integrate quite so well as MPF with the rest of GMP - as well as an additional rounding mode it uses a default value of NaN rather than zero for new objects which is not ideal from Wren's perspective.

I have therefore decided to stick with MPF for basic arithmetic, for which it is perfectly adequate, but use MPFR for the transcendental functions. There are 21 such functions which I thought it would be worthwhile supporting and, as the wrapper converts automatically between the MPF and MPFR types, this is transparent to the user.

### How fast?

Early results suggest Wren-gmp will be significantly faster than Wren-big for scripts requiring a lot of 'big number' arithmetic. However, writers of Wren-cli scripts which require file handling or other stuff which embedded Wren doesn't support 'out of the box' may prefer to stick to the former rather than make one off changes to the C executable.

Of course, the speed improvement doesn't mean that Wren will be able to compete with the statically typed compiled languages which use GMP or a similar package - it won't. Even though Wren's embedding API is quite fast and GMP/MPFR are very fast, this won't compensate for the fact that Wren is interpreted and uses double precision floating point for all numeric work even when only integers are required.

In practice GMP may use a higher precision.     If integers are required, Nums which are not integers will be truncated towards zero by GMP.*/foreign class Mpf is Comparable {     // Creates small commonly used Mpf objects with default precision.    static minusOne { from(-1)   }    static zero     { new()      }    static one      { from(1)    }    static two      { from(2)    }    static three    { from(3)    }    static four     { from(4)    }    static five     { from(5)    }    static ten      { from(10)   }    static half     { from(0.5)  }    static third    { new().inv(three) }    static quarter  { from(0.25) }    static fifth    { from(0.2)  }    static tenth    { from(0.1)  }      // Creates transcendental constants with a specified precision.    static e(prec)     { from(1, prec).exp  }                // E    static ln2(prec)   { from(2, prec).log  }                // natural log of 2    static ln10(prec)  { from(10, prec).log }                // natural log of 10    static pi(prec)    { new(prec).acos(Mpf.zero).mul(2) }   // Pi    static tau(prec)   { new(prec).acos(Mpf.zero).mul(4) }   // Tau (twice Pi)    static phi(prec)   { from(5, prec).sqrt.add(1).div(2) }  // Phi (golden ratio)    static sqrt2(prec) { from(2, prec).sqrt }                // Square root of 2    static euler(prec) { from(1, prec).digamma.neg }         // Euler's constant     // Convenience versions of the above constants whihc use the default precision.    static e     { from(1).exp  }    static ln2   { from(2).log  }    static ln10  { from(10).log }    static pi    { new().acos(Mpf.zero).mul(2) }    static tau   { new().acos(Mpf.zero).mul(4) }    static phi   { from(5).sqrt.add(1).div(2) }    static sqrt2 { from(2).sqrt }    static euler { from(1).digamma.neg }     // Swaps the values of two Mpf objects.    foreign static swap(op1, op2)     // Splits an Mpf into a double plus an exponent (returned as a list of two Nums).    foreign static frexp(op)     // Gets the string presentation of am Mpf object in base b with up to n digits.    // Returns it as a list containing a digit string and an exponent.    // The digit string has an implicit radix point immediately to the left of the first digit.    foreign static getStr(op, b, n)     // Returns the smaller of two Mpf objects.    static min(op1, op2) {        if (op1 < op2) return op1        return op2    }     // Returns the greater of two Mpf objects.    static max(op1, op2) {        if (op1 > op2) return op1        return op2    }     // Returns the positive difference of two Mpf objects.    static dim(op1, op2) {        if (op1 >= op2) return op1 - op2        return Mpf.zero    }     foreign static defaultPrec         // returns the default precision in bits actually used    foreign static defaultPrec=(prec)  // sets the default precision to at least 'prec' bits     // Creates a new Mpf object with a value of 0 and precision of:    construct new() {}       //  default    construct new(prec) {}   //  at least 'prec' bits     // Convenience methods which create a new Mpf object from any other applicable type    // with default precision.    static from(op)        { new().set(op) }         // any numeric type    static fromStr(str, b) { new().setStr(str, b) }  // a base 'b' string (zero if invalid)    static fromStr(str)    { new().setStr(str, 10) } // a base 10 string (zero if invalid)     // Convenience methods which create a new Mpq object from any other applicable type    // with a precision of at least 'prec' bits.    static from(op, prec) { new(prec).set(op) }               // any numeric type    static fromStr(str, b, prec) { new(prec).setStr(str, b) } // a base 'b' string (zero if invalid)     // Assigns new values to the current instance using :    foreign setMpf(op)              // another Mpf object    foreign setMpq(op)              // an Mpq object    foreign setMpz(op)              // an Mpz object    foreign setDbl(op)              // a double    foreign setUi(op)               // an unsigned integer    foreign setSi(op)               // a signed integer    foreign setStr(str, b)          // a base 'b' string (unchanged if invalid)    setStr(str) { setStr(str, 10) } // a base 10 string     // Convenience method which assigns a new value to the current instance    // from any other numeric type.    set(op) {        if (op is Mpf) return setMpf(op)        if (op is Num) {            if (op.isInteger) return (op >= 0) ?
