in my contract I need to do some calculations to convert some ERC20 tokens value to WEI and I need to do something like:
tokenValueWei(uint) = tokenValue(uint) * multiplier(ufixed)
eg. 100000012 (some token fractions) * 0.0013233 (multiplier) = 132330 (WEI rounded)
while the multiplier is being supplied to the contract by the contract manager. Any way to achieve this?
