Get Square Root of Any Hex Value: PPC ASM

[JoshuaMK]

Here is my new version of this, call it as a function, r3 = number, r4 = rounding type (0 = Standard Rounding, 1 = Round Towards Zero):

Code:

typedef int BOOL;
enum { FALSE, TRUE };

unsigned int squareRoot(unsigned int num, BOOL roundDown) {
    unsigned int i = 0;
    while (i * i < num) i = i + 1;
    if (roundDown == TRUE || (i * i) - num > num - (i - 1) * (i - 1)) return i - 1;
    else return i;
}
