Kotlin multiplatform porting of Java's BigInteger and BigDecimal.
Currently this library is only compatible with common and jvm modules.
Any PR implementing is platforms are more than welcome.
The project is split into two different packages: biginteger and bigdecimal (which depends on biginteger).
The library is available on Jitpack. In order to get it, you have to do as follows.
1. Add the Jitpack repository to your project build.gradle file.
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}2. Add the dependency you prefer. All the dependencies can be used as follows
dependencies {
"com.github.komputing.kbignumbers:{module}-{platform}:{version}"
}Examples:
dependencies {
"com.github.komputing.kbignumbers:biginteger-common:1.0.0-RC1"
"com.github.komputing.kbignumbers:bigdecimal-jvm:1.0.0-RC1"
}| Module | Description |
|---|---|

bigdecimal |
Contains the `BigDecimal class definition |
| Platform | Description |
|---|---|
