MpxUseusePrecision
响应式地设置数字的精度。
用法
ts
import { usePrecision } from '@mpxjs/moxuse-math'
const value = ref(3.1415)
const result = usePrecision(value, 2) // 3.14
const ceilResult = usePrecision(value, 2, {
math: 'ceil'
}) // 3.15
const floorResult = usePrecision(value, 3, {
math: 'floor'
}) // 3.141
import { usePrecision } from '@mpxjs/moxuse-math'
const value = ref(3.1415)
const result = usePrecision(value, 2) // 3.14
const ceilResult = usePrecision(value, 2, {
math: 'ceil'
}) // 3.15
const floorResult = usePrecision(value, 3, {
math: 'floor'
}) // 3.141
