Float32

Definitions

def abs(x: Float32): Float32Source

Returns the absolute value of x.

def ceil(x: Float32): Float32Source

Returns x rounded up to a Float32 representing the nearest larger integer value.

def clampToInt16(x: Float32, minimum: Int16, maximum: Int16, nanValue: Int16): Int16Source

Convert 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: Float32, minimum: Int32, maximum: Int32, nanValue: Int32): Int32Source

Convert 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: Float32, minimum: Int64, maximum: Int64, nanValue: Int64): Int64Source

Convert 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: Float32, minimum: Int8, maximum: Int8, nanValue: Int8): Int8Source

Convert 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: Float32): Float32Source

Returns x rounded down to a Float32 representing the nearest smaller integer value.

def fromString(s: String): Option[Float32]Source

Parse the string s as a Float32, leading or trailing whitespace is trimmed. A successful parse is wrapped with Some(x), a parse failure is indicated by None.

def isFinite(x: Float32): BoolSource

Returns true if and only if x is a non-infinite and non-Nan Float32 value.

def isInfinite(x: Float32): BoolSource

Returns true if and only if x is an infinite and non-Nan Float32 value.

def isNan(x: Float32): BoolSource

Returns true if and only if x is the NaN value of type Float32.

def max(x: Float32, y: Float32): Float32Source

Returns the larger of x and y.

def maxExponent(_unit: Unit): Int32Source

Returns the maximum exponent that a Float32 may have.

def maxValue(_unit: Unit): Float32Source

Returns the maximum number representable by a Float32.

def min(x: Float32, y: Float32): Float32Source

Returns the smaller of x and y.

def minExponent(_unit: Unit): Int32Source

Returns the minimum exponent that a Float32 may have.

def minPositiveValue(_unit: Unit): Float32Source

Returns the minimum positive number representable by a Float32.

def minValue(_unit: Unit): Float32Source

Returns the minimum number representable by a Float32.

def nan(_unit: Unit): Float32Source

Returns the NaN (not a number) value of type Float32.

def negativeInfinity(_unit: Unit): Float32Source

Returns the negative infinity value of type Float32.

def positiveInfinity(_unit: Unit): Float32Source

Returns the positive infinity value of type Float32.

def pow(b: Float32, n: Float32): Float32Source

Returns b raised to the power of n.

def round(x: Float32): Float32Source

Returns x rounded to a Float32 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(0.5f32) == 0.0f32).

def size(_unit: Unit): Int32Source

Returns the number of bits used to represent a Float32.

def toFloat64(x: Float32): Float64Source

Convert x to an Float64.

def toString(x: Float32): StringSource

Return a string representation of x.

def tryToBigDecimal(x: Float32): Option[BigDecimal]Source

Convert 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: Float32): Option[BigInt]Source

Convert 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 tryToInt16(x: Float32): Option[Int16]Source

Convert 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: Float32): Option[Int32]Source

Convert 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.

Note: while the range of an Int32 is precisely defined using Int32 values, converting this range to Float32 values is imprecise.

def tryToInt64(x: Float32): Option[Int64]Source

Convert 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 Float32 values is imprecise.

def tryToInt8(x: Float32): Option[Int8]Source

Convert 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.
