What it does

Warns for mistyped suffix in literals

Why is this bad?

This is most probably a typo

Known problems

  • Does not match on integers too large to fit in the corresponding unsigned type
  • Does not match on _127 since that is a valid grouping for decimal and octal numbers

Example

`2_32` => `2_i32`
`250_8 => `250_u8`
