public static double hypot (double x, double y)

Returns sqrt(x² +y²) without intermediate overflow or underflow.

Special cases:

• If either argument is infinite, then the result is positive infinity.
• If either argument is NaN and neither argument is infinite, then the result is NaN.

The computed result must be within 1 ulp of the exact result. If one parameter is held constant, the results must be semi-monotonic in the other parameter.

Parameters:

x		a value
y		a value

Returns:  sqrt(x² +y²) without intermediate overflow or underflow

Since:  1.5
