EXPM1(3) Linux Programmer's Manual EXPM1(3)NAMEexpm1, log1p - exponential minus 1, logarithm of 1 plus argumentSYNOPSIS#include <math.h> double expm1(double x); double log1p(double x);DESCRIPTIONexpm1(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 inaccu- rate 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 TOBSDSEE ALSOexp(3), log(3)GNU1995-09-16 EXPM1(3)
