Lodash mixins for arbitrary-precision arithmetic
npm install lodash-arithmetic> Lodash mixins for arbitrary-precision arithmetic
You will find a complete explanation about floating-point arithmetic at http://floating-point-gui.de/.
Lodash-arithmetic provides simple Lo-Dash mixins for basic arithmetic operations: addition, subtraction, multiplication and division.
Even if Lo-Dash 4 natively has the methods _.add, _.subtract, _.multiply and _.divide, they do not take in account arbitrary-precision decimal.
Let's see the following examples:
``js
// Without Lo-Dash
console.log(0.1 + 0.2 === 0.3) // false
// With Lo-Dash 4 but without the arithmetic mixins
console.log(_.add(0.1, 0.2) === 0.3) // false
// With Lo-Dash and the arithmetic mixins
console.log(_.add(0.1, 0.2) === 0.3) // true
`
as dependency:
`sh
npm install lodash-arithmetic --save
`Usage
##### Addition
js
_.add(0.1, 0.2); // 0.3
`
##### Subtraction
js
_.subtract(0.1235, 0.1234); // 0.0001
`
##### Multiplication
js
_.multiply(0.07, 100); // 7
`
##### Division
js
_.divide(8.2, 1000); // 0.0082
`
##### Chaining
js
_(0.1)
.add(0.2)
.multiply(77.1)
.subtract(0.12345)
.value(); // 23.00655
