integer

Integers come in two varieties -- fixnums and bignums. Fixnums fit in a machine word and are faster to manipulate; if the result of a fixnum operation is too large to fit in a fixnum, the result is upgraded to a bignum. Here is an example where two fixnums are multiplied yielding a bignum:




Integers can be entered using a different base; see Number syntax.

Integers can be tested for, and real numbers can be converted to integers:

fixnum? ( object -- ? )

bignum? ( object -- ? )

>fixnum ( x -- n )

>integer ( x -- n )

>bignum ( x -- n )
