float       hypotf( float x, float y );
double      hypot( double x, double y );
long double hypotl( long double x, long double y );
Calcule la racine carrée de la somme des carrés des x et y, sans trop-plein indue ou négatif durant les étapes intermédiaires du calcul. Il s'agit de la longueur de l'hypoténuse d'un triangle rectangle dont les côtés sont de longueur et x y, ou la distance de la (x,y) point à l'origine (0,0), ou l'amplitude d'un nombre complexe x+iy
Original:
Computes the square root of the sum of the squares of x and y, without undue overflow or underflow at intermediate stages of the computation. This is the length of the hypotenuse of a right-angled triangle with sides of length x and y, or the distance of the point (x,y) from the origin (0,0), or the magnitude of a complex number x+iy
