CORDIC MATH IN C The

THE FOLLOWING WAS INVENTED BY FOLKS FAR SMARTER THEN ME I'M JUST TRYING TO MAKE IT A FUNCTIONAL C LIBRARY THAT DOSEAS MUCH AS I CAN WITH + - BIT SHIFTS AND FIX POINT

  the CORDIC algorithm for sin and cos where z starts as the angle x at 1 y at 0 and i is number of iterations. 
This is a kinda c kinda psudo code version of it  as you can see sin and cos are both found at once atanz is a array of 20 atan( 2^-i)*(1<<20) the 20 bitshift is because this is all done in fix point 32 bit int Q=20 so thats where the decimal falls 20 binary places from the back 

struct sincos  CORDIC_sin_cos( float ang){
int y, x, z, ny, nx ;
    x =1*(1<<20);
    y = 0;
    z=(int32_t) ang * (1<<20);
for ( int i = 0 ; i  < 20 ; i++ ){
     if ( z <0 ){
        nx = x + ( y >> i ) ;
        ny = y - ( x >> i) ;
        z += atanz[ i ] ;
    }else{
        nx = x - ( y >> i ) ;
        ny = y + ( x >> i ) ;
        z -= atanz[ i ] ;
    }
    x = nx ;
    y = ny ;
}
    struct sincos{
        float sin =(float) y / (1<<20) ;
        float cos =(float) x / (1<<20) ;
    }sincos;
return sincos ;
}

 since tan is  sin/cos  thats your basic trig functions asin  can be found by entering the sin  the target and running the formula to push the y  to the target then getting the z which starts at 0 for this . Acos can be done the same way if it is positive if it is negitive  it is the same as asin( abs( input ) ) + pi /2

LOGARITHMIC MATH

BODWITCH NAPIER AND HOW TO MAKE MATH EASY

Ok so here is where I am with the use of log and exp allthou I have a sorta working CORDIC function for both log and exp it's only sorta working and this is kinda way cooler also it works.

Using exp :

There is actually more but that should give you an idea there is also e and the hyperbolic I spelt that right and messed up spelled so bad spell check didn't even understand me left spelling error left because back to the point:f

on the all log exp bitshift version of asinh and acosh I may be a bit off im not sure if the plus and minus 1 are in the right spot atanh is actualy easier:

so after saying all that
