When using coerce_str to parse a uint from a decimal number in non-wei units, precision is lost due to use of f64. For example, parsing 123456.123456789123456789 ether returns 123456123456789126578176 wei, but the correct value is 123456123456789123456789 wei.
Solution
I removed uses of f64, and all math is now done using U256 only. This also means std is no longer required when parsing decimal numbers with coerce_str.
I also added test cases that fail without this change.
