一、使用方法
1、在使用的页面引入
import { JSAdd,JSSub,JSDiv, JSMul } from '../../until/jsOperation'1、对需要计算的数值
JSDiv(除数, 被除数) 如:10000/100 JSAdd(10000, 100) JSSub(10000, 100) JSMul(10000, 100) JSDiv(10000, 100) JSDiv(bargainAmountMin, 100) JSMul()的用法亦如此二、方法 1、加法
export function JSAdd (a, b) { if (!a || !b) { return a + b } let c, d try { c = a.toString().split('.')[1].length } catch (f) { c = 0 } try { d = b.toString().split('.')[1].length } catch (f) { d = 0 } const h = Math.pow(10, Math.max(c, d)) return (JSMul(a, h) + JSMul(b, h)) / h }2、减法
export function JSSub (a, b) { if (!a || !b) { return a - b } let c, d try { c = a.toString().split('.')[1].length } catch (f) { c = 0 } try { d = b.toString().split('.')[1].length } catch (f) { d = 0 } const h = Math.pow(10, Math.max(c, d)) return (JSMul(a, h) - JSMul(b, h)) / h }3、乘法
export function JSMul (a, b) { if (!a || !b) { return 0 } let c = 0 const d = a.toString() const e = b.toString() try { if (d.split('.')[1]) { c += d.split('.')[1].length } } catch (f) { console.log(f) } try { if (e.split('.')[1]) { c += e.split('.')[1].length } } catch (f) { console.log(f) } const result = (Number(d.replace('.', '')) * Number(e.replace('.', ''))) / Math.pow(10, c) return result }4、除法
export function JSDiv (a, b) { if (!a || !b) { return 0 } let e = 0 let f = 0 try { if (a.toString().split('.')[1]) { e = a.toString().split('.')[1].length } } catch (g) { console.log(g) } try { if (b.toString().split('.')[1]) { f = b.toString().split('.')[1].length } } catch (g) { console.log(g) } const result = JSMul( Number(a.toString().replace('.', '')) / Number(b.toString().replace('.', '')), Math.pow(10, f - e) ) return result }
