Specification

Math

\[\begin{array}{l} \\ \frac{x}{y \cdot 3} \end{array} \]

FPCore

(FPCore (x y) :precision binary64 (/ x (* y 3.0)))

C

double code(double x, double y) {
	return x / (y * 3.0);
}

Fortran

real(8) function code(x, y)
    real(8), intent (in) :: x
    real(8), intent (in) :: y
    code = x / (y * 3.0d0)
end function

Java

public static double code(double x, double y) {
	return x / (y * 3.0);
}

Python

def code(x, y):
	return x / (y * 3.0)

Julia

function code(x, y)
	return Float64(x / Float64(y * 3.0))
end

MATLAB

function tmp = code(x, y)
	tmp = x / (y * 3.0);
end

Wolfram

code[x_, y_] := N[(x / N[(y * 3.0), $MachinePrecision]), $MachinePrecision]
