EXPM1 Section: Linux Programmer's Manual (3) Updated: September 16, 2025 Index   NAME expm1, log1p - exponential minus 1, logarithm of 1 plus argument   SYNOPSIS #include <math.h> double expm1 ( double x ); double log1p ( double x );   DESCRIPTION expm1(x) returns a value equivalent to `exp (x) - 1'. It is computed in a way that is accurate even if the value of x is near zero--a case where `exp (x) - 1' would be inaccurate due to subtraction of two numbers that are nearly equal. log1p(x) returns a value equivalent to `log (1 + x)'. It is computed in a way that is accurate even if the value of x is near zero.   CONFORMING TO BSD   SEE ALSO   Index NAME SYNOPSIS DESCRIPTION CONFORMING TO SEE ALSO This document was created by using the manual pages.
