Converting Ramda-Based Validation Logic to Schema

import { always, curry, ifElse, last, lte, pipe, split, toString } from 'ramda'

const validateMaxDecimals = curry((number: number, maxDecimals: number) => {
  const decimalStr = pipe(
    toString,
    split('.'),
    ifElse((xs) => xs.length > 1, last, always(''))
  )

  const numDecimals = (decimalStr(number) as string).length
  return lte(numDecimals, maxDecimals)
})
