  • The C compiler, when I parse a &(float) as (long) (it's actually an evil floating point hack to run Quake III on an X86_64 CPU emulated in Scratch running on Spotifys Car Thing) (This would never be possible in Rust)

    Yes, but

    1. it's unsafe, therefore not really Rust I'd argue
    2. it doesn't look as good
    float Q_rsqrt(float number) {
   long i;
   float x2, y;
   const float threehalfs = 1.5F;

   x2 = number * 0.5F;
   y = number;

   i = * ( long * ) &y;
   i = 0x5f3759df - ( i >> 1 );
   y = * ( float * ) &i;

   y = y * ( threehalfs - ( x2 * y * y ) );
   return y;
}
