{{DISPLAYTITLE:_HYPOT}}
|
|
The [[_HYPOT]] function returns the hypotenuse of a right-angled triangle whose legs are x and y.
|
|
|
|
|
|
{{PageSyntax}}
|
|
: {{Parameter|result!}} = [[_HYPOT]]({{Parameter|x}}, {{Parameter|y}})
|
|
|
|
|
|
{{Parameters}}
|
|
* {{Parameter|x}} and {{Parameter|y}} are the floating point values corresponding to the legs of a right-angled (90 degree) triangle for which the hypotenuse is computed.
|
|
|
|
|
|
{{PageDescription}}
|
|
* 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
