Hello,I am after a fast floor function; In fact a fast truncation and conversion to integer. I see that std.math takes a real, and that std.c.math takes a double.Is there a quicker function, and what might cast(int)1.5f do? Regards, Spacen.
If you don't need to handle negatives, I suggest you simply use a cast(int) since truncation has both a x87 instruction (FISTTP) and a SSE instruction (CVTTSS2SI).
