Hi Thundergnat.
Regarding the Perl 6 solution of the checking Machin Style formulas. The problem is that the Perl 6 solution uses floating point numbers. The task requires one to use exact computations.
For example:
is tan(atan(1/2)+atan(1/3)), 1;
Here atan(1/2) and atan(1/3) produces floating point values.
