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 ) ); // 1st iteration
// y = y * ( threehalfs - ( x2 * y * y ) ); // 2nd iteration, this can be removed
return y;
}
is a piece of art.

making a constant for threehalfs and then throwing 0x5f3759df at you fours lines later makes me kek every time

does this offer any performance gain?
does it even work nowadays?

No the closest approximation is sorcery or magic

God's Temple is the greatest work of programming art.

NO, STOP AND THINK.
Programming IS NOT AN ART. Programming is a cold, pragmatic discipline that want to bring order to the chaotic world that surround us. The programmer grab pieces of reality and make them dance in a song he only can hear. The monotone song the programmer does is fueled by his desire of order and logic, knowing that that chaos entities are always trying to defy and break the precious balance his mind and cold calculations created.

Maybe go to school again and learn how calculating a root works, retard
Connor White
It offers a performance gain because it approximates a very costly operation (inverse square root) without doing any division at all.
It would work nowadays but be unnecessary since CPUs are much more powerful than in 1999.

well duh?, I am a Java programmer.

The magic circle algorithm is cool as fuck:
x = x - e * y
y = y + e * x

Some math info. I ran into it in a thread about pulsing Arduino lights t b h.

someone plz explain is it calling a memory location?

It's really mathematics that's an art form.

Someone explain to a brainlet how 1/sqrt(x) is used to compute angles of incidence and reflection for lighting and shading visually?
Robert Johnson
I love this because even the person who wrote it can't explain how he came up with the magic number
A mathematician even came up with a more accurate number but it somehow ran slower
