I have come to an inexplicable (at least for me at the moment) behavior in Julia julia> using Dates julia> Dates.value(Minute(60)) / 1 * 38.849 2330.9399999999996 julia> Dates.value(Dates.value(Minute(60)) * 38.849 2330.9399999999996 julia> Dates.value(Minute(60)) / 10 * 38.849 233.094 julia> Dates…

That question is common enough that there’s a PSA: [image] PSA: floating-point arithmetic Offtopic Sometimes people are surprised by the results of floating-point calculations such as julia> 5/6 0.8333333333333334 # shouldn't the last di…

This isn’t about Dates, but rather that floating point arithmetic doesn’t work quite how one may expect. See: 3.8849 == 38.849/10 # false This isn’t even about Julia, since Julia implements the industry standard IEEE 754 that most languages do. Essentially, if you’re using floats you can’t usuall…

Thanks for your replies :slight_smile: Just in case for future readers, what I actually wanted to ask has it answers here :smiley:
