!!!EXP ---- !!NAME exp, log, log10, pow - exponential, logarithmic and power functions !!SYNOPSIS __#include __ ''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 sqrt(3), cbrt(3) ----
