Number numberic validation

[Elaskin]

I would like to have numeric action that applies to number schema
Numeric as in sql numeric example :
numeric(10,5)
valid: 12345.12000/12345.12/1.12345
invalid: 12345.123456/123456.12345

I am not sure how to handle percision errors though

Hey 👋 I'm not sure what the best way to solve this challenge, since there are only numbers and bigints in JavaScript. One solution might be to use .toFixed(5). You can either convert the number to a valid number or return an error if .toFixed(5) changes the number passed. Checkout this playground.

import * as v from 'valibot';

const Schema1 = v.pipe(
  v.number(),
  v.transform((i) => Number(i.toFixed(5))),
);

const Schema2 = v.pipe(
  v.number(),
  v.check(
    (i) => Number(i.toFixed(5)) === i,
    'Up to 5 fraction digits are allowed',
  ),
);
