/**
* Computes the greatest common divisor (gcd).
*
* ## Notes
*
* -   If both `a` and `b` are `0`, the function returns `0`.
* -   Both `a` and `b` must have integer values; otherwise, the function returns `NaN`.
*
* @param a - integer
* @param b - integer
* @returns greatest common divisor
*
* @example
* var v = gcd( 48, 18 );
* // returns 6
*
* @example
* var v = gcd( 3.14, 18 );
* // returns NaN
*
* @example
* var v = gcd( NaN, 18 );
* // returns NaN
