hypotl()

long double hypotl	(	long double	x,
		long double	y
	)

Compute hypotenuse.

The hypotl functions compute the square root of the sum of the squares of x and y, without undue overflow or underflow. A range error may occur.

Parameters

x	Floating point value corresponding to the leg of a right-angled triangle for which the hypotenuse is computed.
y	Floating point value corresponding to the leg of a right-angled triangle for which the hypotenuse is computed.

Returns

The hypotl functions return √(x^2+y^2).
