heinrich5991 9911759314 Revert "Don't divide by 0" 
This reverts commit 03faa51e28.

Dividing floats by zero isn't undefined behavior and results in +inf or
-inf depending on the sign of the first operand.

	#include <math.h>
	#include <stdio.h>

	#define PRINT(x) printf("%s = %f\n", #x, x)

	int main()
	{
		PRINT(1.0 / 0.0);
		PRINT(-1.0 / 0.0);
		PRINT(atanf(1.0 / 0.0));
		PRINT(atanf(-1.0 / 0.0));
		return 0;
	}

prints

	1.0 / 0.0 = inf
	-1.0 / 0.0 = -inf
	atanf(1.0 / 0.0) = 1.570796
	atanf(-1.0 / 0.0) = -1.570796

The changed function was problematic for values like (0,1), (-1,0),
(0,-1) where it always returned an angle of 0°.
