Purpose
This module provides functions to convert fractional probabilities (e.g. `0.01`) into human-friendly text strings such as:
- `"no chance"`
- `"100% chance"`
- `"about 1 in 100"`
- `"almost zero chance (less than 1 in 1,000,000)"`
It is designed for use in templates where probabilities need to be expressed in plain language.
Usage
Basic syntax:
{{#invoke:ProbabilityFormat|convert|probability|cutoff}}
probability(required) — a number between `0` and `1`.cutoff(optional) — probabilities smaller than this are treated as “almost zero chance.” Defaults to `1e-6` (1 in 1,000,000).
Parameters
probability- The fractional probability, either as a number or string (e.g. `0.05`).
cutoff- A fractional cutoff for “almost zero” reporting. For example, passing `1e-4` will show “less than 1 in 10,000.”
