Float64
Definitions
def ceil(x: Float64): Float64SourceReturns x rounded up to a Float64 representing the nearest larger integer value.
def clampToFloat32(x: Float64, minimum: Float32, maximum: Float32): Float32SourceConvert x to a Float32.
Returns x clamped within the Float32 range minimum to maximum.
def clampToInt16(x: Float64, minimum: Int16, maximum: Int16, nanValue: Int16): Int16SourceConvert x to an Int16.
Returns x clamped within the Int16 range minimum to maximum.
Warning: it is recommended to test x for NaN (not-a-number) before calling this
function. Relying on nanValue to convert NaN to a permissable Int16 risks masking it.
def clampToInt32(x: Float64, minimum: Int32, maximum: Int32, nanValue: Int32): Int32SourceConvert x to an Int32.
Returns x clamped within the Int32 range minimum to maximum.
Warning: it is recommended to test x for NaN (not-a-number) before calling this
function. Relying on nanValue to convert NaN to a permissable Int32 risks masking it.
def clampToInt64(x: Float64, minimum: Int64, maximum: Int64, nanValue: Int64): Int64SourceConvert x to an Int64.
Returns x clamped within the Int64 range minimum to maximum.
Warning: it is recommended to test x for NaN (not-a-number) before calling this
function. Relying on nanValue to convert NaN to a permissable Int64 risks masking it.
def clampToInt8(x: Float64, minimum: Int8, maximum: Int8, nanValue: Int8): Int8SourceConvert x to an Int8.
Returns x clamped within the Int8 range minimum to maximum.
Warning: it is recommended to test x for NaN (not-a-number) before calling this
function. Relying on nanValue to convert NaN to a permissable Int8 risks masking it.
def floor(x: Float64): Float64SourceReturns x rounded down to a Float64 representing the nearest smaller integer value.
def fromString(s: String): Option[Float64]SourceParse the string s as a Float64, leading or trailing whitespace is trimmed.
A successful parse is wrapped with Some(x), a parse failure is indicated by None.
def isFinite(x: Float64): BoolSourceReturns true if and only if x is a non-infinite and non-Nan Float64 value.
def isInfinite(x: Float64): BoolSourceReturns true if and only if x is an infinite and non-Nan Float64 value.
def minPositiveValue(_unit: Unit): Float64SourceReturns the minimum positive number representable by a Float64.
def negativeInfinity(_unit: Unit): Float64SourceReturns the negative infinity value of type Float64.
def positiveInfinity(_unit: Unit): Float64SourceReturns the positive infinity value of type Float64.
def round(x: Float64): Float64SourceReturns x rounded to a Float64 representing the nearest integer value.
The rounding may be upwards or downwards. If the rounding up and rounding down are equally
close, x will be rounded to an even value (i.e. round(0.5f64) == 0.0f64).
def tryToBigDecimal(x: Float64): Option[BigDecimal]SourceConvert x to an Option[BigDecimal].
Returns Some(x as BigDecimal) if the numeric value of x is representable
as a BigDecimal value.
If x is NaN or infinity return None.
def tryToBigInt(x: Float64): Option[BigInt]SourceConvert x to an Option[BigInt].
Returns Some(x as BigInt) if the numeric value of x is representable as a BigInt.
Returns None if the value of x is NaN or infinity.
def tryToFloat32(x: Float64): Option[Float32]SourceConvert x to an Option[Float32].
Returns Some(x as Float32) if the numeric value of x is within the range
of Float32, loss of precision may occur.
Returns None if the numeric value of x is outside the range of Float32
(i.e. 1.4E-45 to 3.4028235E38).
If x is NaN return Some(Float32.NaN)`, if x is positive or negative infinity return
Some wrapping the corresponding Float32 infinity.
def tryToInt16(x: Float64): Option[Int16]SourceConvert x to an Option[Int16].
Returns Some(x as Int16) if the numeric value of x is within the range
of Int16, rounding x towards 0`.
Returns None if the numeric value of x is outside the range of Int16
(i.e. -32768 to 32767), or it is NaN or infinity.
def tryToInt32(x: Float64): Option[Int32]SourceConvert x to an Option[Int32].
Returns Some(x as Int32) if the numeric value of x is within the range
of Int32, rounding x towards 0`.
Returns None if the numeric value of x is outside the range of Int32
(i.e. -2147483648 to 2147483647), or it is NaN or infinity.
def tryToInt64(x: Float64): Option[Int64]SourceConvert x to an Option[Int64].
Returns Some(x as Int64) if the numeric value of x is within the range
of Int64, rounding x towards 0`.
Returns None if the numeric value of x is outside the range of Int64
(i.e. -9223372036854775808 to 9223372036854775807), or it is NaN or infinity.
Note: while the range of an Int64 is precisely defined using Int64 values, converting this range to Float64 values is imprecise.
def tryToInt8(x: Float64): Option[Int8]SourceConvert x to an Option[Int8].
Returns Some(x as Int8) if the numeric value of x is within the range
of Int8, rounding x towards 0`.
Returns None if the numeric value of x is outside the range of Int8
(i.e. -128 to 127), or it is NaN or infinity.
