go-string2eth

Go utility library to convert strings to Ether values and vice versa.

When converting strings to numeric values the process is case-insensitive and doesn't care about whitespace, so input values such as "0.1 Ether", "0.1Ether" and "0.1ether" would all result in the same result. The standard unit denominations (Wei, Ether) are supported with or without SI prefixes (micro, milli, kilo, mega etc.), as are common names (Shannon, Babbage).

When converting numeric values to strings the user can select standard mode, in which case all values will be in units of Wei or Ether, or non-standard mode, in which case the full range of values will be used.

This also provides the ability to convert between string and GWei values.
