Step: NumbersToExpressions

Constructor key: NumbersToExpressions

Rewrites number literals as arithmetic expressions and optionally mutates numeric representation format.

Settings

Key Type Default Notes
Threshold number 1 probability 0..1 for transforming number literals
InternalThreshold number 0.2 recursion/representation cutoff (0..0.8)
NumberRepresentationMutation boolean false enables representation mutation
AllowedNumberRepresentations table { "hex", "scientific", "normal" } options include binary

Example

{
  Name = "NumbersToExpressions",
  Settings = {
    Threshold = 1,
    InternalThreshold = 0.2,
    NumberRepresentationMutation = true,
    AllowedNumberRepresentations = { "hex", "scientific", "normal" },
  }
}

Notes

  • If binary is enabled in allowed representations, Prometheus warns that binary literals need Lua 5.2+ syntax support.
  • Legacy key NumberRepresentationMutaton is still accepted for backward compatibility.
