See awesome math below

eiπ=−1e^{i\pi} = -1

Section 3#

info

The code block below is very important. It has highlighting, file name, and line highlighting!

/src/fastInvSqrt.c
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;
