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)
