EXP(2)								System Calls Manual							    EXP(2)

NAME
       exp, log, log10, pow, pow10, sqrt - exponential, logarithm, power, square root

SYNOPSIS
       #include <u.h>
       #include <libc.h>

       double exp(double x)

       double log(double x)

       double log10(double x)

       double pow(double x, double y)

       double pow10(int n)

       double sqrt(double x)

DESCRIPTION
       Exp returns the exponential function of x.

       Log returns the natural logarithm of x; log10 returns the base 10 logarithm.

       Pow returns x^y, and pow10 returns 10^n as a double.

       Sqrt returns the square root of x.

SOURCE
       All these routines have portable C implementations in /sys/src/libc/port.  Most also have machine-dependent implementations, written either
       in assembler or C, in /sys/src/libc/$objtype.
