definiert in Header <math.h>
float       hypotf(float x, float y );
double      hypot(double x, double y );
longdouble hypotl(longdouble x, longdouble y );

Berechnet die Quadratwurzel aus der Summe der Quadrate der x und y, ohne unnötige Überlauf oder Unterlauf an Zwischenstufen der Berechnung. Dies ist die Länge der Hypotenuse eines rechtwinkligen Dreiecks mit einer Seitenlänge von Länge und xy, oder der Abstand des Punktes vom Ursprung (x,y)(0,0) oder den Betrag einer komplexen Zahl 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
