Exception for math.cube on real

Math

\[\left(x \cdot x\right) \cdot x \]

FPCore

(FPCore (x) :precision binary64 (* (* x x) x))

C

double code(double x) {
	return (x * x) * x;
}

Fortran

real(8) function code(x)
    real(8), intent (in) :: x
    code = (x * x) * x
end function

Java

public static double code(double x) {
	return (x * x) * x;
}

Python

def code(x):
	return (x * x) * x

Julia

function code(x)
	return Float64(Float64(x * x) * x)
end

MATLAB

function tmp = code(x)
	tmp = (x * x) * x;
end

Wolfram

code[x_] := N[(N[(x * x), $MachinePrecision] * x), $MachinePrecision]
