babel-plugin-transform-jsbd-to-bigdecimal

A scheme similar to JSBI, for transforming JSBD to native bigdecimal, Referring to the implementation of jsbi (https://github.com/GoogleChromeLabs/babel-plugin-transform-jsbi-to-bigint)

how to use

use as a babel plugin @yukinotech/babel-plugin-transform-jsbd-to-bigdecimal

const result = require('@babel/core').transform(code, {
  plugins: ['@yukinotech/babel-plugin-transform-jsbd-to-bigdecimal'],
  comments: false,
})

how it work

it will replace indetitor JSBD to native bigdecimal syntax

| Operation | native BigDecimals | JSBD | | ---------------------------------| -------------------| -----------------------------------------| | Addition | c = a + b | c = JSBD.add(a, b) | | Subtraction | c = a - b | c = JSBD.subtract(a, b) | | Multiplication | c = a * b | c = JSBD.multiply(a, b) | | Division with two arguments | c = a / b | c = JSBD.divide(a, b) | | Remainder | c = a % b | c = JSBD.remainder(a, b) | | Exponentiation | c = a ** b | c = JSBD.pow(a, b) | | Comparison to other BigInts | a === b | JSBD.equal(a, b) | | | a !== b | JSBD.notEqual(a, b) | | | a < b | JSBD.lessThan(a, b) | | | a <= b | JSBD.lessThanOrEqual(a, b) | | | a > b | JSBD.greaterThan(a, b) | | | a >= b | JSBD.greaterThanOrEqual(a, b) | | | c = BigDecimal.round(a,option) | c = JSBD.round(a, option) | | Division with three arguments | c = BigDecimal.divide(a,b,roundOption) | c = JSBD.divide(a, b,roundOption)|

differences from bigint to bigdecimal

since bigdecimal has a roundOption, we can't just transform JSBI.add(one,two) to one + two,if there are three arguments we just transform JSBD.add(one,two,option) to Decimal.add(one,two,option)
