Hello,
I have the problem that Matlab rounds (using floor/fix) the result of my division, 33 / 0.55, towards 59 instead of 60. The code looks like this:
s = floor(a / b)
Where 'a' and 'b' come from a GUI and can be integers or decimals (but never negativ or zero). When I set a = 33 and b = 0.55 and run the program matlab produces as a intermediate result, of a / b, 60.000 (I checked it), which get afterwards rounded by floor (or fix) to 59.
The ultimate goal of the part of the code is to divide 'a' through 'b' and give an integer back, where the integer should be rounded down towards the next integer (1.7 to 1 or 4.9 to 4 etc.).
Thanks for the help!

It is rounded down to the next integer.
format short
33/0.55
ans = 60.0000
format long
33/0.55
ans =
59.999999999999993
It's just a matter of floating point error and display settings.

Hi
Just use:
s=round(a/b)
