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
