• cbrt

function <cmath> <ctgmath> cbrt double cbrt (double x); float cbrtf (float x);long double cbrtl (long double x); double cbrt (double x); float cbrt (float x);long double cbrt (long double x); double cbrt (T x); // additional overloads for integral types Compute cubic root Returns the cubic root of x. Header <tgmath.h> provides a type-generic macro version of this function. Additional overloads are provided in this header (<cmath>) for the integral types: These overloads effectively cast x to a double before calculations (defined for T being any integral type).

Parameters

x Value whose cubic root is computed.

Return Value

Cubic root of x.

Example

123456789101112

/* cbrt example */ #include <stdio.h> /* printf */ #include <math.h> /* cbrt */ int main () { double param, result; param = 27.0; result = cbrt (param); printf ("cbrt (%f) = %f\n", param, result); return 0; }

Output:

cbrt (27.000000) = 3.000000
