Truncates a number, removing the fractional digits toward zero

Demo

Usage

import { useTrunc } from '@reause/math'

const result1 = useTrunc(0.95) // 0
const result2 = useTrunc(-2.34) // -2

value is a plain read-only number. Re-render with a new value — e.g. from useState — and the hook recomputes:

import { useTrunc } from '@reause/math'
import { useState } from 'react'

const [value, setValue] = useState(0.95)
const result = useTrunc(value) // 0

setValue(-2.34) // triggers a re-render

Type Declarations

export function useTrunc(value: number): number
