# 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:0.4.0`.
|
||||
|
||||
**Gradle Kotlin DSL:**
|
||||
```kotlin
|
||||
repositories {
|
||||
maven("https://repo.kotlin.link")
|
||||
mavenCentral()
|
||||
}
|
||||
|
||||
dependencies {
|
||||
implementation("space.kscience:kmath-jafama:0.4.0")
|
||||
}
|
||||
```
|
||||
|
||||
## 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.
