It's Assembly though, assembler would be the compiler itself. You can ask Intel for the IA32 manuals, they're free. Or just download the PDFs from their site. The code is almost entirely taken from a manual. First we load X and Y onto the stack, We then loop until the control flag is cleared. So if the result of TEST is not zero (JNZ), we jump onto the label that we previously declared. We finally pop and we return. FSTSW is simply used to get the condition bits into AX. You may test the routine like so: <pre lang="purebasic">For i=0 To 19 Debug fmod( i*0.1, 0.5 ) Next</pre> Cheers. No problem. It’s Assembly though, assembler would be the compiler itself.

You may test the routine like so:

For i=0 To 19
	Debug fmod( i*0.1, 0.5 )
Next

Cheers.

I thought there was no way of doing this in pure basic. I cant read assembler but I will definitely use this. Could you explain me what the code does though? Thanks!
