Function: fractionDigits()

fractionDigits(raw): number

Defined in: packages/core/src/decimal.ts:557

Counts the digits a raw value writes after its decimal point.

This is XPath's string-length(substring-after($value, '.')), which the UBL-DT-01 and PEPPOL-EN16931-DEC rules apply to the text as it appears in the document: '100.500' has three fraction digits, and a trailing space counts as one.

Parameters

raw

string

The value exactly as it appears in the document, not normalised.

Returns

number

The number of characters after the first decimal point; 0 when there is none.

Example

import { fractionDigits } from '@facturometro/core';

fractionDigits('100.500'); // 3
fractionDigits('100'); // 0
fractionDigits('100.50 '); // 3
