help you fix your problem 4.9 + 0.5 is 5.4, which cannot possibly round to 4 unless your compiler is seriously broken.
I just confirmed that the Googled code gives the correct answer for 4.9.

Hope that helps In my notes I have something like , No. What about this case?
code :
Guard==true
Sticky==false
Round==false
LSB==0

Hope that helps The question is how to round a given value to the nearest "almost exact" multiple of a given factor, f. For example:
code :
double roundUp(double x, double f) {
  return f * Math.ceil(x / f);
}

With these it helps The x87 FPU implements four rounding methods in hardware. Those are :
Round to nearest (even) Round down, towards negative infinity Round up, towards positive infinity Round toward zero

This might help you C or C++ don't care about what you need.
12.555 is not a binary floating point number. Binary floating point numbers are all integers multiplied by or divided by a power of two. 12.555 is not such a number. So when you write 12.555 then what you get is the floating-point number nearest to 12.555. Which may be smaller or larger than 12.555 and will be correctly rounded to 12.55 or correctly rounded to 12.56.

I wish this helpful for you As the title suggests, I want to take a floating point number and round it down to the nearest integer. However, if it's not a whole, I ALWAYS want to round down the variable, regardless of how close it is to the next integer up. Is there a way to do this? , Simple
