Compute the cube root of a number
#include <math.h> double cbrt ( double x ); float cbrtf ( float x );
The cbrt() and cbrtf() functions compute the cube root of x.
The cube root of x. If x is NAN, cbrt() returns NAN.
#include <stdio.h> #include <inttypes.h> #include <math.h> #include <fpstatus.h> int main(int argc, char** argv) { double a, b; a = 27.0; b = cbrt(a); printf("The cube root of %f is %f \n", a, b); return(0); }
produces the output:
The cube root of 27.000000 is 3.000000
