SQRT(3) Library Functions Manual SQRT(3) NAME cbrt, cbrtf, cbrtl, sqrt, sqrtf, sqrtl -- cube root and square root func- tions LIBRARY Math Library (libm, -lm) SYNOPSIS #include <math.h> double cbrt(double x); float cbrtf(float x); long double cbrtl(long double x); double sqrt(double x); float sqrtf(float x); long double sqrtl(long double x); DESCRIPTION The cbrt(), cbrtf(), and cbrtl() functions compute the cube root of x. The sqrt(), sqrtf(), and sqrtl() functions compute the non-negative square root of x. RETURN VALUES The cbrt(), cbrtf(), and cbrtl() functions return the requested cube root. The sqrt(), sqrtf(), and sqrtl() functions return the requested square root unless an error occurs. An attempt to take the sqrt() of negative x raises an invalid exception and causes an NaN to be returned (except that the square root of -0 is valid and equal to -0.) SEE ALSO fenv(3), math(3) STANDARDS The cbrt(), cbrtf(), cbrtl(), sqrt(), sqrtf(), and sqrtl() functions con- form to ISO/IEC 9899:1999 ("ISO C99"). HISTORY The cbrt() function appeared in 4.3BSD. The sqrtl() function appeared in FreeBSD 8.0. The cbrtl() function appeared in FreeBSD 9.0. FreeBSD 9.0 March 5, 2011 SQRT(3)
