5.4 Numbers

Librep lacks exact number specification. The behavior depends on if it is compiled with gmp support or not. Of course, some feautures are not available without gmp².

If it is compiled without gmp, then the size of integer type also depends on the platform. Size of integer is 30-bit signed at minimum.

If portability is important, like sawfish, then you should expect the minimum. For more information, See Types of Numbers.

For conversion of number from / to string, see See String Functions.
