struct

Public Struct Fixed32 Implements Numeric, Comparable, Hashable, Bounded, Printable, Defaultable

A number with 16 bits for its whole part, its sign among them, and 16 after the point: from -32768 to 32767.99998, in steps of 1 / 65536.

Examples

Local three = Fixed32.FromInt(3)
Local four = Fixed32.FromInt(4)
Expect((three / four).ToDouble() == 0.75)
Expect(three * four == Fixed32.FromInt(12))
Expect(Fixed32.FromDouble(1.5).Raw == 98304)
Expect(Sqrt(Fixed32.FromInt(16)) == four)

Public Static Method FromRaw(bits: Int32): Fixed32 static method #

The Fixed32 these bits are, as Raw gives them.
@PanicsAtCaller Public Static Method FromInt(value: Int): Fixed32 static method #

The whole number. One outside -32768 to 32767 panics.
@PanicsAtCaller Public Static Method FromDouble(value: Double): Fixed32 static method #

The Double, rounded to the nearest Fixed32, halves away from 0. One outside a Fixed32's range, or NaN, panics.
@PanicsAtCaller Public Static Method FromFloat(value: Float): Fixed32 static method #

The Float, rounded to the nearest Fixed32, halves away from 0. One outside a Fixed32's range, or NaN, panics.
Public Static Method Zero(): Fixed32 static method #

The zero Fixed32, which adding leaves alone.
Public Static Method One(): Fixed32 static method #

The Fixed32 1, raw 65536, which multiplying leaves alone.
Public Static Method DefaultValue(): Fixed32 static method #

The zero Fixed32.
Public Static Method MinValue(): Fixed32 static method #

The lowest Fixed32, -32768.
Public Static Method MaxValue(): Fixed32 static method #

The highest Fixed32, about 32767.99998.
Public Static Method DoubleValue(value: Fixed32): Double static method #

The value as a Double, which holds every one exactly.
Public Static Property Pi: Fixed32 property #

Pi, and a turn, 2 Pi, rounded to a Fixed32's steps.
Public Static Property Tau: Fixed32 property #

A turn, 2 Pi, rounded to a Fixed32's steps.
Public Property Raw: Int32 property #

The value's bits, the value times 65536.
Public Method ToDouble(): Double method #

The value as a Double, which holds it exactly.
Public Method ToFloat(): Float method #

The value as a Float, rounded to the nearest.
Public Method ToInt(): Int method #

The whole part, toward 0, as As takes a Float's.
Public Method ToFixed64(): Fixed64 method #

The value as a Fixed64, which holds it exactly.
Public Method ToString(): String method #

Its value, as the Double it is shows.
@PanicsAtCaller Operator +(a: Fixed32, b: Fixed32): Fixed32 operator #

a plus b. Panics in a debug build when it's past what a Fixed32 holds, and wraps in a release one.
@PanicsAtCaller Operator -(a: Fixed32, b: Fixed32): Fixed32 operator #

a minus b. Panics in a debug build when it's past what a Fixed32 holds, and wraps in a release one.
@PanicsAtCaller Operator -(a: Fixed32): Fixed32 operator #

a negated.
Operator <(a: Fixed32, b: Fixed32): Bool operator #

Whether a is less than b.
@PanicsAtCaller Operator *(a: Fixed32, b: Fixed32): Fixed32 operator #

a times b. Panics in a debug build when it's past what a Fixed32 holds, and wraps in a release one. Rounded to the nearest.
@PanicsAtCaller Operator *(a: Fixed32, b: Int): Fixed32 operator #

a times b.
@PanicsAtCaller Operator *(a: Int, b: Fixed32): Fixed32 operator #

a times b.
@PanicsAtCaller Operator /(a: Fixed32, b: Fixed32): Fixed32 operator #

a divided by b. A b of 0 panics, and a quotient past what it holds does as + does.
@PanicsAtCaller Operator /(a: Fixed32, b: Int): Fixed32 operator #

a divided by b.
