Float is used to represent a 64-bit floating point number.
Slots
- abs
-
Float abs()
Return the absolute value of this float. If this value is positive then return this, otherwise return the negation.
- acos
-
Float acos()
Return the arc cosine.
- approx
-
Bool approx(Float r, Float tolerance := def)
Return if this Float is approximately equal to the given Float by the specified tolerance. If tolerance is null, then it is computed using the magnitude of the two Floats. It is useful for comparing Floats since often they loose a bit of precision during manipulation. This method is equivalent to:
if (tolerance == null) tolerance = min(abs(this/1e6), abs(r/1e6)) (this - r).abs < tolerance
- asin
-
Float asin()
Return the arc sine.
- atan
-
Float atan()
Return the arc tangent.
- atan2
-
static Float atan2(Float y, Float x)
Converts rectangular coordinates (x, y) to polar (r, theta).
- bits
-
Int bits()
Return 64-bit representation according IEEE 754 floating-point double format bit layout. This method is paired with
Float.makeBits
. - bits32
-
Int bits32()
Return 32-bit representation according IEEE 754 floating-point single format bit layout. This method is paired with
Float.makeBits32
. - ceil
-
Float ceil()
Returns the smallest whole number greater than or equal to this number.
- compare
-
Compare based on floating point value.
- cos
-
Float cos()
Return the cosine of this angle in radians.
- cosh
-
Float cosh()
Return the hyperbolic cosine.
- decrement
-
Float decrement()
Decrement by one. Shortcut is --a or a--.
- e
-
static Float e
Float value for e which is the base of natural logarithms.
- equals
-
Return true if same float value. Unlike Java, NaN equals NaN.
- exp
-
Float exp()
Return e raised to this power.
- floor
-
Float floor()
Returns the largest whole number less than or equal to this number.
- fromStr
-
static Float fromStr(Str s, Bool checked := def)
Parse a Str into a Float. Representations for infinity and not-a-number are "-INF", "INF", "NaN". This string format matches the lexical representation of Section 3.2.5 of XML Schema Part 2. If invalid format and checked is false return null, otherwise throw ParseErr.
TODO: need spec - follow XML Schema literal definition
- hash
-
override Int hash()
Return bits().
- increment
-
Float increment()
Increment by one. Shortcut is ++a or a++.
- log
-
Float log()
Return natural logarithm of this number.
- log10
-
Float log10()
Return base 10 logarithm of this number.
-
new make()
Private constructor.
- makeBits
-
static Float makeBits(Int bits)
Make a Float for the specified 64-bit representation according IEEE 754 floating-point double format bit layout. This method is paired with
Float.bits
. - makeBits32
-
static Float makeBits32(Int bits)
Make a Float for the specified 32-bit representation according IEEE 754 floating-point single format bit layout. This method is paired with
Float.bits32
. - max
-
Return the larger of this and the specified Float values.
- min
-
Return the smaller of this and the specified Float values.
- minus
-
Subtract b from this. Shortcut is a-b.
- nan
-
static Float nan
Float value for Not-A-Number.
- negInf
-
static Float negInf
Float value for negative infinity.
- negate
-
Float negate()
Negative of this. Shortcut is -a.
- percent
-
Return remainder of this divided by b. Shortcut is a%b.
- pi
-
static Float pi
Float value for pi which is the ratio of the circumference of a circle to its diameter.
- plus
-
Add this with b. Shortcut is a+b.
- posInf
-
static Float posInf
Float value for positive infinity.

-
Return this value raised to the specified power.
- round
-
Float round()
Returns the nearest whole number to this number.
- sin
-
Float sin()
Return sine of this angle in radians.
- sinh
-
Float sinh()
