The [_HYPOT](_HYPOT) function returns the hypotenuse of a right-angled triangle whose legs are x and y.
|
||
|
|
|
||
|
|
## Syntax
|
||
|
|
|
||
|
|
> result! = [_HYPOT](_HYPOT)(x, y)
|
||
|
|
|
||
|
|
## Parameter(s)
|
||
|
|
|
||
|
|
* 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
|
||
|
|
|
||
|
|
## Example(s)
|
||
|
|
|
||
|
|
```vb
|
||
|
|
|
||
|
|
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
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
```text

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