# fixhypot(3alleg)

Fixed point hypotenuse. Allegro game programming library.

## NAME

fixhypot - Fixed point hypotenuse. Allegro game programming library.

## SYNOPSIS

**#include \<allegro.h\>**

**fixed fixhypot(fixed x, fixed y);**

## DESCRIPTION

Fixed point hypotenuse (returns the square root of \`x\*x + y\*y'). This should be better than calculating the formula yourself manually, since the error is much smaller.
