Package-level declarations

Types

abstract class Random

A Guest pseudorandom source. Seeded generators and Default are reproducible on Compukters; their sequences are independent of Kotlin/JVM implementations. Not a cryptographic source. Each call executes ordinary metered Guest instructions.

Functions

nextInt

fun Random.nextInt(range: IntRange): Int

Uniform value in the inclusive range, including the full Int domain.

nextLong

fun Random.nextLong(range: LongRange): Long

Uniform value in the inclusive range, including the full Long domain.

nextUBytes

fun Random.nextUBytes(size: Int): UByteArray

fun Random.nextUBytes(array: UByteArray): UByteArray

fun Random.nextUBytes(array: UByteArray, fromIndex: Int, toIndex: Int): UByteArray

Fills exactly [fromIndex, toIndex); invalid ranges do not consume state or modify the array.

nextUInt

fun Random.nextUInt(): UInt

Unsigned full-width bits from this source.

fun Random.nextUInt(until: UInt): UInt

fun Random.nextUInt(range: UIntRange): UInt

Uniform value in the inclusive range, including the full UInt domain.

fun Random.nextUInt(from: UInt, until: UInt): UInt

Uniform value in [from, until), using rejection before modulo reduction.

nextULong

fun Random.nextULong(): ULong

Unsigned full-width bits from this source.

fun Random.nextULong(until: ULong): ULong

fun Random.nextULong(range: ULongRange): ULong

Uniform value in the inclusive range, including the full ULong domain.

fun Random.nextULong(from: ULong, until: ULong): ULong

Uniform value in [from, until), using rejection before modulo reduction.

Random

fun Random(seed: Int): Random

Independent reproducible generator; Int seeds sign-extend to Long.

fun Random(seed: Long): Random

Independent reproducible generator with all 64 seed bits retained.
