6.6.2 Numerical data types

Guile supports a rich “tower” of numerical types — integer, rational, real and complex — and provides an extensive set of mathematical and scientific functions for operating on numerical data. This section of the manual documents those types and functions.

You may also find it illuminating to read R5RS’s presentation of numbers in Scheme, which is particularly clear and accessible: see Numbers in R5RS.
