EXP Section: Linux Programmer's Manual (3) Updated: June 16, 2025 Index   NAME exp, log, log10, pow - exponential, logarithmic and power functions   SYNOPSIS #include <math.h> double exp(double x); double log(double x); double log10(double x); double pow(double x, double y);   DESCRIPTION The exp() function returns the value of e (the base of natural logarithms) raised to the power of x. The log() function returns the natural logarithm of x. The log10() function returns the base-10 logarithm of x. The pow() function returns the value of x raised to the power of y.   ERRORS The log() and log10() functions can return the following errors: EDOM The argument x is negative. ERANGE The argument x is zero. The log of zero is not defined. The pow() function can return the following error: EDOM The argument x is negative and y is not an integral value. This would result in a complex number.   CONFORMING TO SVID 3, POSIX, BSD 4.3, ISO 9899   SEE ALSO   Index NAME SYNOPSIS DESCRIPTION ERRORS CONFORMING TO SEE ALSO This document was created by using the manual pages.
