PyF.Formatters
Description
Formatters for integral / fractional and strings.
Is support:
For all types:
- Grouping of the integral part (i.e: adding a custom char to separate groups of digits)
- Padding (left, right, around, and between the sign and the number)
- Sign handling (i.e: display the positive sign or not)
For floating:
- Precision
- Fixed Exponential Generic formatting
For integrals:
- Binary Hexa Octal / Character representation
Synopsis
- formatString :: Maybe (Int, AlignMode AlignAll, Char) -> Maybe Int -> String -> String

- formatFractional :: RealFloat f => Format t t' Fractional -> SignMode -> Maybe (Int, AlignMode k, Char) -> Maybe (Int, Char) -> Maybe Int -> f -> String
