    ECMA Section:       15.8.2.12 Math.min(x, y)
    Description:        return the smaller of the two arguments.
                        special cases:
                            - if x is NaN or y is NaN   return NaN
                            - if x < y                  return x
                            - if y > x                  return y
                            - if x is +0 and y is +0    return +0
                            - if x is +0 and y is -0    return -0
                            - if x is -0 and y is +0    return -0
                            - if x is -0 and y is -0    return -0
