_hypot (Windows CE 5.0)
Developing an Application > Microsoft C Run-time Library for Windows CE > Run-time Library Reference
Calculates the hypotenuse.
double _hypot( doublex,doubley);
Parameters
- x, y
Floating-point values
Libraries
All versions of the C run-time libraries.
Return Values
_hypot returns the length of the hypotenuse if successful or INF (infinity) on overflow.
Remarks
The _hypot function calculates the length of the hypotenuse of a right triangle, given the length of the two sides x and y.
A call to _hypot is equivalent to the square root of x2 + y2.
Example
/* HYPOT.C: This program prints the
* hypotenuse of a right triangle.
*/
void main( void )
{
double x = 3.0, y = 4.0;
printf( "If a right triangle has sides %2.1f and %2.1f, "
"its hypotenuse is %2.1f\n", x, y, _hypot( x, y ) );
}
Output
If a right triangle has sides 3.0 and 4.0, its hypotenuse is 5.0
Requirements
OS Versions: Windows CE 2.0 and later.
Header: stdlib.h.
Link Library: coredll.dll.
