Defined in header <math.h>
float       hypotf( float x, float y );
double      hypot( double x, double y );
long double hypotl( long double x, long double y );
Calcula a raiz quadrada da soma dos quadrados dos x e y, sem excesso indevido ou underflow nas fases intermédias do cálculo. Este é o comprimento da hipotenusa de um triângulo rectângulo com lados de comprimento e x y, ou a distância entre o ponto a partir do (x,y) (0,0) origem, ou a magnitude de um número complexo 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
