Float64
Definitions
def ceil(x: Float64): Float64
SourceReturns x
rounded up to a Float64 representing the nearest larger integer value.
def clampToFloat32(x: Float64, minimum: Float32, maximum: Float32): Float32
SourceConvert x
to a Float32
.
Returns x
clamped within the Float32 range minimum
to maximum
.
def clampToInt16(x: Float64, minimum: Int16, maximum: Int16, nanValue: Int16): Int16
SourceConvert 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): Int32
SourceConvert 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): Int64
SourceConvert 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): Int8
SourceConvert 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): Float64
SourceReturns 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): Bool
SourceReturns true if and only if x
is a non-infinite and non-Nan Float64
value.
def isInfinite(x: Float64): Bool
SourceReturns true if and only if x
is an infinite and non-Nan Float64
value.
def minPositiveValue(_unit: Unit): Float64
SourceReturns the minimum positive number representable by a Float64
.
def negativeInfinity(_unit: Unit): Float64
SourceReturns the negative infinity value of type Float64
.
def positiveInfinity(_unit: Unit): Float64
SourceReturns the positive infinity value of type Float64
.
def round(x: Float64): Float64
SourceReturns 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.
