Multiply the number by the number of decimals you want to save, then round, then divide it back again. Use github.com/shopspring/decimal, which is a package for "arbitrary-precision fixed-point decimal numbers in go". It can "only" represent numbers with a maximum of 2^31 digits after the decimal point. Use float64, and convert all your ints into floats before calculations.
