.ig @(#)exp.3m 2.1 7/1/84 @(#)Copyright (C) 1983 by National Semiconductor Corp. .. .TH EXP 3M .SH NAME exp, log, log10, pow, sqrt \- exponential, logarithm, power, square root .SH SYNOPSIS .nf .B #include <math.h> .PP .B double exp(x) .B double x; .PP .B double log(x) .B double x; .PP .B double log10(x) .B double x; .PP .B double pow(x, y) .B double x, y; .PP .B double sqrt(x) .B double x; .fi .SH DESCRIPTION .I Exp returns the exponential function of .I x. .PP .I Log returns the natural logarithm of .IR x ; .I log10 returns the base 10 logarithm. .PP .I Pow returns .I x\u\s8y\s10\d. .PP .I Sqrt returns the square root of .I x. .SH SEE ALSO hypot(3), sinh(3), intro(2) .SH DIAGNOSTICS .I Exp and .I pow return a huge value when the correct value would overflow; .I errno is set to ERANGE. .I Pow returns 0 and sets .I errno to EDOM when the second argument is negative and non-integral and when both arguments are 0. .PP .I Log returns 0 when .I x is zero or negative; .I errno is set to EDOM. .PP .I Sqrt returns 0 when .I x is negative; .I errno is set to EDOM.
