1 Vue project installation Decimal
npm install
2 Note
The result of the operation is a Decimal object, and you need to use .toNumber() to convert it to a number.
3 plus add
const Decimal = require('')
const num1 = Decimal("5");
const num2 = Decimal("3");
const remainder = (num2);
4 minus sub
const Decimal = require('')
const num1 = Decimal("5");
const num2 = Decimal("3");
const remainder = (num2);
5 by mul
const Decimal = require('')
const num1 = Decimal("5");
const num2 = Decimal("3");
const remainder = (num2);
6 except div
const Decimal = require('')
const num1 = Decimal("5");
const num2 = Decimal("3");
const remainder = (num2);
7 Find the rest module
const Decimal = require('')
const num1 = Decimal("5");
const num2 = Decimal("3");
const remainder = (num2);Appendix: Use vue to solve the problem of missing accuracy of total sum of decimals
- Installation dependencies
- npm install --save
- Package
- Create a file under the utils folder
import { Decimal } from ''
export function add (x, y) {
if (!x) {
x = 0
}
if (!y) {
y = 0
}
const xx = new Decimal(x)
const yy = new Decimal(y)
return (yy).toNumber()
}
// reduceexport function sub (x, y) {
if (!x) {
x = 0
}
if (!y) {
y = 0
}
const xx = new Decimal(x)
const yy = new Decimal(y)
return (yy).toNumber()
}
// removeexport function div (x, y) {
if (!x) {

}
if (!y) {
return 0
}
const xx = new Decimal(x)
const yy = new Decimal(y)
return (yy).toNumber()
}
//takeexport function mul (x, y) {
if (!x) {

}
if (!y) {

}
const xx = new Decimal(x)
const yy = new Decimal(y)
return (yy).toNumber()
