float       hypotf( float x, float y );
double      hypot( double x, double y );
long double hypotl( long double x, long double y );
計算の中間段階での過度のオーバーフローまたはアンダーフローが発生することなく、xとyの二乗和の平方根を計算します。これは、長さの辺をもつ直角三角形の斜辺の長さxとy、または起点(x,y)、または複素数(0,0)の大きさから点x+iyの距離
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
