Machine_float

Description

Numerical characteristics of the machine for floats. Contains analogues of much of the double precision details of .Machine.

Usage

Machine_float

Format

A list containing:

• float.eps epsilon

• float.xmin smallest non-zero float

• float.xmax largest non-inf float

• float.base radix

• float.digits the number of bits for the sign+significand

• float.exponent number of bits for the exponent

• float.min.exp "largest negative" (smallest) integer for the exponent that generates a normalized floating-point number

• float.max.exp largest integer for the exponent that generates a normalized floating-point number

Details

Values are taken directly from float.h.
