sign: Int

The sign of this number.

Returns 0 for 0, 0.0, -0.0, and NaN, 1 for positive numbers (including Infinity), and -1 for negative numbers (including -Infinity).

link

abs: Int

The absolute value of this number.

Facts:

42.abs == 42

0.0.abs == 0.0
(-0.0).abs == 0.0
Infinity.abs == Infinity
(-Infinity).abs == Infinity

link

ceil: Int

Rounds this number to the next mathematical integer towards Infinity.

If this is an Int, returns this. If this is NaN, Infinity, -Infinity, 0.0, or -0.0, returns this. Otherwise, returns the smallest Float that is greater than or equal to this and is equal to a mathematical integer.
link

floor: Int

Rounds this number to the next mathematical integer towards -Infinity.

If this is an Int, returns this. If this is NaN, Infinity, -Infinity, 0.0, or -0.0, returns this. Otherwise, returns the largest Float that is less than or equal to this and is equal to a mathematical integer.

link

isPositive: Boolean

Tells if this number is greater than or equal to zero.

Facts:

0.isPositive
(-0).isPositive
0.0.isPositive
(-0.0).isPositive
3.isPositive
3.14.isPositive
Infinity.isPositive

!(-3).isPositive
!(-3.14).isPositive
!(-Infinity).isPositive
!NaN.isPositive

link

isFinite: Boolean

Tells if this number is neither NaN nor isInfinite.
link

isInfinite: Boolean

Tells if this number is Infinity or -Infinity.
link

isNaN: Boolean

Tells if this number is NaN.

Always use this method when testing for NaN. Note that x == NaN is not a correct way to test for NaN because NaN != NaN as per the IEEE spec.
link

isNonZero: Boolean

Tells if this number is not 0.
link

inv: Int

Bitwise NOT (inverse) of this integer.
link

isEven: Boolean

Tells if this integer is evenly divisible by two.
link

isOdd: Boolean

Tells if this number is not isEven.

Methods(show inherited)

link

function

Any.getClass(): Class (pkl.base)

Returns the class of this.
link

function

toString(): String

Converts this number to its decimal string representation.
link

function

Any.ifNonNull<Result>(transform: (NonNull) -> Result): Result? (pkl.base)

Returns this |> transform if this is non-null, and null otherwise.

This method is the complement of the ?? operator and the equivalent of an Option type's map and flatMap methods.
link

function

round(): Int

Rounds this number to the nearest mathematical integer, breaking ties in favor of the even integer.

If this is an Int, returns this. If this is NaN, Infinity, -Infinity, 0.0, or -0.0, returns this. Otherwise, return the Float that is nearest to this and is equal to a mathematical integer. If two mathematical integers are equally near, returns the even integer.
link

function

truncate(): Int

Rounds this number to the next mathematical integer towards zero.

If this is an Int, returns this. If this is NaN, Infinity, -Infinity, 0.0, or -0.0, returns this. If this is less than zero, returns the smallest Float that is greater than or equal to this and is equal to a mathematical integer. Otherwise, returns the largest Float that is less than or equal to this and is equal to a mathematical integer.
link

function

toInt(): Int

Converts this number to an Int.

If this is an Int, returns this. If this is NaN, Infinity, or -Infinity, throws an error. Otherwise, returns the Int representation for this.truncate(). If this.truncate() is not representable in (that is, too large for) Int, throws an error.
link

function

toFloat(): Float

Converts this number to a Float.

If this is a Float, returns this. Otherwise, returns the Float representation for this. If this is not representable in Float, returns the Float nearest to this.
link

function

toFixed(fractionDigits: Int(this.isBetween(0, 20))): String

Converts this number to a decimal fixed-point representation with fractionDigits digits after the decimal point.
link

function

toDuration(unit: DurationUnit): Duration

Converts this number to a duration with this value and the given unit.
link

function

toDataSize(unit: DataSizeUnit): DataSize

Converts this number to a data size with this value and the given unit.
link

function
isBetween(start: Number, inclusiveEnd: Number): Boolean

Tells if this number is greater than or equal to start and less than or equal to inclusiveEnd.
Facts:
```
3.2.isBetween(2.6, 4)
3.2.isBetween(2.6, 3.2)
3.2.isBetween(3.2, 4)
!3.2.isBetween(1, 3.1)
```
link

function
toRadixString(radix: Int(this.isBetween(2, 36))): String

Converts this number to a string representation in the given radix.
Digits above 9 are converted to lowercase letters a to z. To pad the resulting string with zeros, use String.padStart().

Facts:
```
(-1).toRadixString(20) == "-1"
42.toRadixString(16) == "2a"
```
link

function

link

function

shr(n: Int): Int

Shifts this integer right by n bits, preserving the sign bit.
link

function

ushr(n: Int): Int

Shifts this integer right by n bits, setting the sign bit to zero.

This operation is known as unsigned right shift.
link
