Double

class Double : Number, Comparable<Double>

Represents a double-precision 64-bit IEEE 754 floating point number. On the JVM, non-nullable values of this type are represented as values of the primitive type double.

Functions

compareTo	operator fun compareTo(other: Byte): Int operator fun compareTo(other: Short): Int operator fun compareTo(other: Int): Int operator fun compareTo(other: Long): Int operator fun compareTo(other: Float): Int operator fun compareTo(other: Double): Int Compares this value with the specified value for order. Returns zero if this value is equal to the specified other value, a negative number if it's less than other, or a positive number if it's greater than other.
dec	operator fun dec(): Double Decrements this value.
div	operator fun div(other: Byte): Double operator fun div(other: Short): Double operator fun div(other: Int): Double operator fun div(other: Long): Double operator fun div(other: Float): Double operator fun div(other: Double): Double Divides this value by the other value.
inc	operator fun inc(): Double Increments this value.
minus	operator fun minus(other: Byte): Double operator fun minus(other: Short): Double operator fun minus(other: Int): Double operator fun minus(other: Long): Double operator fun minus(other: Float): Double operator fun minus(other: Double): Double Subtracts the other value from this value.
plus	operator fun plus(other: Byte): Double operator fun plus(other: Short): Double operator fun plus(other: Int): Double operator fun plus(other: Long): Double operator fun plus(other: Float): Double operator fun plus(other: Double): Double Adds the other value to this value.
rem	operator fun rem(other: Byte): Double operator fun rem(other: Short): Double operator fun rem(other: Int): Double operator fun rem(other: Long): Double operator fun rem(other: Float): Double operator fun rem(other: Double): Double Calculates the remainder of dividing this value by the other value.
times	operator fun times(other: Byte): Double operator fun times(other: Short): Double operator fun times(other: Int): Double operator fun times(other: Long): Double operator fun times(other: Float): Double operator fun times(other: Double): Double Multiplies this value by the other value.
toByte	fun toByte(): Byte Returns the value of this number as a Byte, which may involve rounding or truncation.
toChar	fun toChar(): Char Returns the Char with the numeric value equal to this number, truncated to 16 bits if appropriate.
toDouble	fun toDouble(): Double Returns the value of this number as a Double, which may involve rounding.
toFloat	fun toFloat(): Float Returns the value of this number as a Float, which may involve rounding.
toInt	fun toInt(): Int Returns the value of this number as an Int, which may involve rounding or truncation.
toLong	fun toLong(): Long Returns the value of this number as a Long, which may involve rounding or truncation.
toShort	fun toShort(): Short Returns the value of this number as a Short, which may involve rounding or truncation.
unaryMinus	operator fun unaryMinus(): Double Returns the negative of this value.
unaryPlus	operator fun unaryPlus(): Double Returns this value.

Companion Object Properties

MAX_VALUE	val MAX_VALUE: Double A constant holding the largest positive finite value of Double.
MIN_VALUE	val MIN_VALUE: Double A constant holding the smallest positive nonzero value of Double.
NEGATIVE_INFINITY	val NEGATIVE_INFINITY: Double A constant holding the negative infinity value of Double.
NaN	val NaN: Double A constant holding the "not a number" value of Double.
POSITIVE_INFINITY	val POSITIVE_INFINITY: Double A constant holding the positive infinity value of Double.

Extension Functions

coerceAtLeast	fun Double.coerceAtLeast(minimumValue: Double): Double Ensures that this value is not less than the specified minimumValue.
coerceAtMost	fun Double.coerceAtMost(maximumValue: Double): Double Ensures that this value is not greater than the specified maximumValue.
coerceIn	fun Double.coerceIn( minimumValue: Double, maximumValue: Double ): Double Ensures that this value lies in the specified range minimumValue..maximumValue.
isFinite	fun Double.isFinite(): Boolean Returns `true` if the argument is a finite floating-point value; returns `false` otherwise (for `NaN` and infinity arguments).
isInfinite	fun Double.isInfinite(): Boolean Returns `true` if this value is infinitely large in magnitude.
isNaN	fun Double.isNaN(): Boolean Returns `true` if the specified number is a Not-a-Number (NaN) value, `false` otherwise.
rangeTo	operator fun Double.rangeTo( that: Double ): ClosedFloatingPointRange<Double> Creates a range from this Double value to the specified other value.
