@:ihavenomouth: not reading all that happy for you or sorry that float Q_rsqrt( float number ){ long i; float x2, y;
const float threehalfs = 1.5F;
x2 = number * 0.5F;
y = number;
i = * ( long * ) &y; // evil floating point bit level hacking
i = 0x5f3759df - ( i >> 1 ); // what the fuck?
y = * ( float * ) &i;
y = y * ( threehalfs - ( x2 * y * y ) );
// y = y * ( threehalfs - ( x2 * y * y ) );
return y;
