CommonBigInt

class CommonBigInt : BigInt, BigIntConstructor

Types

Companion

object Companion : BigIntCompanion

DivRem

data class DivRem(val div: CommonBigInt, val rem: CommonBigInt)

OpStats

data class OpStats(var iterations: Int = 0, var bigMultiplications: Int = 0, var square: Int = 0)

Properties

absoluteValue

val absoluteValue: CommonBigInt

data

val data: UInt16ArrayZeroPad

dummy

var dummy: Boolean

isNegative

open val isNegative: Boolean

Determines if this BigInt is negative

isNegativeOrZero

open val isNegativeOrZero: Boolean

Determines if this BigInt is either negative or zero (non-positive)

isNotZero

open val isNotZero: Boolean

Determines if this BigInt is not 0

isOne

val isOne: Boolean

isPositive

open val isPositive: Boolean

Determines if this BigInt is positive

isPositiveOrZero

open val isPositiveOrZero: Boolean

Determines if this BigInt is either positive or zero (non-negative)

isSmall

val isSmall: Boolean

isZero

open val isZero: Boolean

Determines if this BigInt is 0

maxBits

val maxBits: Int

significantBits

val significantBits: Int

signum

open override val signum: Int

Returns -1, 0 or +1 depending on the sign of this BigInt

Functions

abs

open override fun abs(): CommonBigInt

Returns this BigInt as positive or zero. Equivalent to if (isNegative) -this else this

and

open infix override fun and(other: BigInt): CommonBigInt

Returns a new BigInt with bits combining this, other doing a bitwise &/and operation. Forces sign to positive.

compareTo

open operator override fun compareTo(that: BigInt): Int

countBits

fun countBits(): Int

create

open override fun create(value: Int): BigInt

open override fun create(value: Long): BigInt

open override fun create(value: String): BigInt

open override fun create(value: String, radix: Int): BigInt

div

open operator override fun div(other: BigInt): CommonBigInt

Returns a new BigInt this this / other

open operator override fun div(other: Int): CommonBigInt

Returns this / other

divRem

fun divRem(other: CommonBigInt): CommonBigInt.DivRem

equals

open operator override fun equals(other: Any?): Boolean

getBit

fun getBit(n: Int): Boolean

getBitInt

fun getBitInt(n: Int): Int

hashCode

open override fun hashCode(): Int

inv

open override fun inv(): CommonBigInt

Returns a new BigInt with its bits flipped. 0 converts into 1, and 1 into 0. Equivalent to -(this + 1)

leadingZeros

fun leadingZeros(): Int

Number of leadingZeros with the size of maxBits

minus

open operator override fun minus(other: BigInt): CommonBigInt

Returns a new BigInt this this - other

open operator override fun minus(other: Int): CommonBigInt

Returns this - other

mulAddSmall

fun mulAddSmall(mul: Int, add: Int): CommonBigInt

mulWithStats

fun mulWithStats(other: CommonBigInt, stats: CommonBigInt.OpStats?): CommonBigInt

open infix override fun or(other: BigInt): CommonBigInt

Returns a new BigInt with bits combining this, other doing a bitwise |/or operation. Forces sign to positive.

plus

open operator override fun plus(other: BigInt): CommonBigInt

Returns a new BigInt this this + other

open operator override fun plus(other: Int): CommonBigInt

Returns this + other

pow

open infix override fun pow(exponent: BigInt): CommonBigInt

open infix override fun pow(exponent: Int): CommonBigInt

Returns this BigInt raised to exponent : this ** exponent

powWithStats

fun powWithStats(exponent: Int, stats: CommonBigInt.OpStats?): CommonBigInt

rangeTo

open operator fun rangeTo(that: BigInt): BigIntRange

Creates a new inclusive BigIntRange ranging from this to that

rem

open operator override fun rem(other: BigInt): CommonBigInt

Returns a new BigInt this this % other

open operator override fun rem(other: Int): CommonBigInt

Returns this % other

shl

open infix override fun shl(count: Int): CommonBigInt

Returns a new BigInt with bits from this shifted to the left count. Equivalent to multiply by 2**count. Keeps the sign of this

shr

open infix override fun shr(count: Int): CommonBigInt

Returns a new BigInt with bits from this shifted to the left count. Equivalent to divide by 2**count. Keeps the sign of this

square

open override fun square(): CommonBigInt

Square of this number. Equivalent this * this, but might be faster in some implementations.

times

open operator override fun times(other: BigInt): CommonBigInt

Returns a new BigInt this this * other

open operator override fun times(other: Int): CommonBigInt

open operator override fun times(other: Long): CommonBigInt

Returns this * other

toBigInteger

fun BigInt.toBigInteger(): <Error class: unknown class>

Converts a BigInt into a BigInteger

toBigNum

fun toBigNum(): BigNum

toInt

open override fun toInt(): Int

Converts this number to a Int. Throws a BigIntOverflowException in the case the number is too big to be stored in an Int

toString

open override fun toString(): String

fun toString(sb: StringBuilder, radix: Int)

open override fun toString(radix: Int): String

Converts this number to a String using the specified radix. The radix is the base to use. 10 for decimal. 16 for hexadecimal.

trailingZeros

fun trailingZeros(): Int

Number of trailingZeros with the size of maxBits

unaryMinus

open operator override fun unaryMinus(): CommonBigInt

Returns a new BigInt with its sign changed. In the case of 0, it returns itself.

unaryPlus

open operator override fun unaryPlus(): CommonBigInt

Returns this BigInt. A convenience method to make explicit the sign and to have symmetry with unaryMinus.

withBit

fun withBit(bit: Int, set: Boolean = true): CommonBigInt

xor

open infix override fun xor(other: BigInt): CommonBigInt

Returns a new BigInt with bits combining this, other doing a bitwise ^/xor operation. Forces sign to positive.
