Platforms

Targets

Platform	Targets
JVM	Java 8 or later
JavaScript	Node.js and browsers (IR compiler)
Kotlin/Native, Apple	macosArm64, iosArm64, iosX64, iosSimulatorArm64, watchosArm32, watchosArm64, watchosDeviceArm64, watchosSimulatorArm64, tvosArm64, tvosSimulatorArm64
Kotlin/Native, Linux	linuxX64, linuxArm64
Kotlin/Native, Windows	mingwX64
Kotlin/Native, Android NDK	androidNativeArm32, androidNativeArm64, androidNativeX86, androidNativeX64

Every Kotlin/Native target is supported, except the ones Kotlin deprecated (macosX64, watchosX64, tvosX64).

Implementations

BigInteger.of, BigDecimal.of and BigFactory.default create the fastest implementation of each platform:

Platform	BigInteger	BigDecimal
JVM	java.math.BigInteger (adapter)	java.math.BigDecimal (adapter)
JavaScript	native BigInt	Kotlin port of java.math.BigDecimal, on BigInt-backed BigIntegers
Kotlin/Native	Kotlin port of java.math.BigInteger; C kernels for multiplication, squaring and Montgomery multiplication (modPow) on 64-bit targets	Kotlin port of java.math.BigDecimal

BigRational is the same Kotlin class everywhere, on top of the platform's BigDecimals and BigIntegers.

Languages

Language	How
Kotlin	any target, org.gciatto.kt.math package
Java	the JVM artifact; factories are static methods, Kotlin extensions are in the Conversions class
JavaScript	the kt-math npm package; overloads have distinct names (see the @JsName annotations in the API reference)
C	a Kotlin/Native shared library and header, prebuilt for Linux, macOS and Windows in the GitHub releases: see Getting started in C and Call Kt-Math from C
