Function: parseFixedValue()

parseFixedValue(input_str): DecimalValue | FractionValue | TextValue

Parse a single quantity value string into a fixed value.

A number-like input is parsed into a DecimalValue or FractionValue; anything else is returned as a TextValue. This is the value-level inverse of formatSingleValue.

Parameters

input_str

string

The raw value string (e.g. "1.5", "1/2", "a pinch")

Returns

DecimalValue | FractionValue | TextValue

The parsed fixed value

Example

parseFixedValue("1.5"); // { type: "decimal", decimal: 1.5 }
parseFixedValue("1/2"); // { type: "fraction", num: 1, den: 2 }
parseFixedValue("a pinch"); // { type: "text", text: "a pinch" }
