Implicit type conversion: Difference between revisions

=={{header|XPL0}}==

XPL0 doesn't have implicit type conversions. It only has two basic data

types: integer and real. Conversions must be done explicitly. For

example:

<syntaxhighlight lang "XPL0">

int I;

real R;

I:= fix(R);

R:= float(I);

</syntaxhighlight>

There is a third declaration type called 'character' (usually abbreviated

'char'). Its variables are the same as integers except when they are

indexed, as for arrays. An indexed character variable accesses bytes,

whereas an indexed integer variable accesses integers.

Strings are one-dimensional arrays consisting of bytes containing ASCII

characters.

Booleans are represented by integers. Zero is false, and non-zero is

true.

Real literals are distinguished from integers by including a decimal point or exponent. For example: 12. or 6e12
