I meant rounding isn't what i need. So when truncating, it probably makes sense to choose the "nicest" decimal representation out of all that could correspond to the value in memory. If you are forced to use floats (say, you're accelerating your code with numba), it's better to use cents as "internal representation" of prices: (70*3 == 210) and multiply/divide the inputs/outputs. Sadly, numpy.trunc function doesn't allow decimal truncation. Allow non-GPL plugins in a GPL main program. numpy result = round(2.5678, 1). If this is your situation, if you do want to use "nice" decimal representations for truncation, all you can do (as far as I know) is pick some number of digits, less than the full precision representable by a float, and round the number to that many digits before truncating it. So the method has to catch this case and handle it differently. How can I fix it?

If that argument is a floating-point literal, you can just cut it off a certain number of places after the decimal point and return that. Ready to optimize your JavaScript with Rust? In earlier versions of Python (up to 2.6, or 3.0), the floating point number formatting was a lot more crude, and would regularly produce things like. Am also a python newbie and after making use of some bits and pieces here, I offer my two cents, str(int(time.time())) will take the time epoch as int and convert it to string and join with The round() function will return the number If you actually are working with floats that are very close to round numbers but intentionally not equal to them (like 0.29999999999999998 or 99.959999999999994), this will produce some false positives, i.e. Something can be done or not a fit?
