# Module kmath-jafama
|
|
|
|
Integration with [Jafama](https://github.com/jeffhain/jafama).
|
|
|
|
- [jafama-double](src/main/kotlin/space/kscience/kmath/jafama/) : Double ExtendedField implementations based on Jafama
|
|
|
|
|
|
## Artifact:
|
|
|
|
The Maven coordinates of this project are `space.kscience:kmath-jafama:0.3.1-dev-1`.
|
|
|
|
**Gradle Groovy:**
|
|
```groovy
|
|
repositories {
|
|
maven { url 'https://repo.kotlin.link' }
|
|
mavenCentral()
|
|
}
|
|
|
|
dependencies {
|
|
implementation 'space.kscience:kmath-jafama:0.3.1-dev-1'
|
|
}
|
|
```
|
|
**Gradle Kotlin DSL:**
|
|
```kotlin
|
|
repositories {
|
|
maven("https://repo.kotlin.link")
|
|
mavenCentral()
|
|
}
|
|
|
|
dependencies {
|
|
implementation("space.kscience:kmath-jafama:0.3.1-dev-1")
|
|
}
|
|
```
|
|
|
|
## Example usage
|
|
|
|
All the `DoubleField` uses can be replaced with `JafamaDoubleField` or `StrictJafamaDoubleField`.
|
|
|
|
```kotlin
|
|
import space.kscience.kmath.jafama.*
|
|
import space.kscience.kmath.operations.*
|
|
|
|
fun main() {
|
|
val a = 2.0
|
|
val b = StrictJafamaDoubleField { exp(a) }
|
|
println(JafamaDoubleField { b + a })
|
|
println(StrictJafamaDoubleField { ln(b) })
|
|
}
|
|
```
|
|
|
|
## Performance
|
|
|
|
According to KMath benchmarks on GraalVM, Jafama functions are slower than JDK math; however, there are indications that on Hotspot Jafama is a bit faster.
