**hypotApx hypotenuse approximation**

**BinaryOperator**

**hypotApx(x, y)**

**x hypotApx: y**

**x.hypotApx(y)**

Returns an approximation of the square root of the sum of the squares of x and y.

The formula used is :

abs(x) + abs(y) - ((sqrt(2) - 1) * min(abs(x), abs(y)))

hypotApx is used to implement Complex method magnitudeApx.

This should not be used for simulating a doppler shift because it is discontinuous. Use hypot.
