CBRT
NAME
cbrt - This function computes the cube root of a number.
SYNOPSIS
cbrt(number)
DESCRIPTION
This mathematical function computes the cube root of a number in the real plane. It returns a number y whose cube is x, meaning that y multiplied by itself 2 times equals x (y*y*y=x). X and y can both be positive or negative.
PARAMETERS
- Number
- Specify the number (float) used as argument for the cbrt function.
RETURN
- Cube root
- The cube root value of the argument.
EXAMPLES
Note: In the followings examples, the _ between the { should be removed to make it work.
One can use this function with a variable :
test(q(res={_{
%include "/includes/extenso.sn";
a=27;
cbrt(a);
}}.),
q(res=3.));
With a trigonometric function:
test(q(res={_{
%include "/includes/extenso.sn";
a=cos(PI);
cbrt(a);
}}.),
q(res=-1.));
With floats:
test(q(res={_{cbrt(0.99);}}.),q(res=.996655.));
With big integers:
test(q(res=3.5568933.),q(res=3.55689.));
With negative numbers:
test(q(res={_{cbrt(-8);}}.),q(res=-2.));
With an array:
test(q(res={_{cbrt(256,0,27);}}.),q(res=\[6.3496,0,3\].));
