The _HYPOT function returns the hypotenuse of a right-angled triangle whose legs are x and y.

## Syntax

*result!*= _HYPOT(*x*,*y*)

## Parameters

*x*and*y*are the floating point values corresponding to the legs of a right-angled (90 degree) triangle for which the hypotenuse is computed.

## Description

- The function returns what would be the square root of the sum of the squares of x and y (as per the Pythagorean theorem).
- The hypotenuse is the longest side between the two 90 degree angle sides

## Examples

*Example:*

* *
DIM leg_x AS DOUBLE, leg_y AS DOUBLE, result AS DOUBLE
leg_x = 3
leg_y = 4
result = _HYPOT(leg_x, leg_y)
PRINT USING "## , ## and ## form a right-angled triangle."; leg_x; leg_y; result

3 , 4 and 5 form a right-angled triangle.
