Float64x2 class - dart:typed_data library (original) (raw)

Float64x2 immutable value type and operations.

Float64x2 stores 2 64-bit floating point values in "lanes". The lanes are "x" and "y" respectively.

It is a compile-time error for a class to attempt to extend or implementFloat64x2.

Constructors

Float64x2(double x, double y)

factory

Float64x2.fromFloat32x4(Float32x4 v)

Uses the "x" and "y" lanes from v.

factory

Float64x2.splat(double v)

factory

Float64x2.zero()

factory

Properties

hashCode → int

The hash code for this object.

no setterinherited

runtimeType → Type

A representation of the runtime type of the object.

no setterinherited

signMask → int

Extract the sign bits from each lane return them in the first 2 bits. "x" lane is bit 0. "y" lane is bit 1.

no setter

x → double

Extracted x value.

no setter

y → double

Extracted y value.

Methods

abs()→ Float64x2

The lane-wise absolute value of this Float64x2.

clamp(Float64x2 lowerLimit, Float64x2 upperLimit)→ Float64x2

Lane-wise clamp this Float64x2 to be in the rangelowerLimit-upperLimit.

max(Float64x2 other)→ Float64x2

The lane-wise maximum value in this Float64x2 or other.

min(Float64x2 other)→ Float64x2

The lane-wise minimum value in this Float64x2 or other.

noSuchMethod(Invocation invocation)→ dynamic

Invoked when a nonexistent method or property is accessed.

inherited

scale(double s)→ Float64x2

Returns a copy of this Float64x2 each lane being scaled by s. Equivalent to this * new Float64x2.splat(s)

sqrt()→ Float64x2

The lane-wise square root of this Float64x2.

toString()→ String

A string representation of this object.

inherited

withX(double x)→ Float64x2

Returns a new Float64x2 copied from this Float64x2 with a new x value.

withY(double y)→ Float64x2

Returns a new Float64x2 copied from this Float64x2 with a new y value.

Operators

operator *(Float64x2 other)→ Float64x2

Multiplication operator.

operator +(Float64x2 other)→ Float64x2

Addition operator.

operator -(Float64x2 other)→ Float64x2

Subtraction operator.

operator /(Float64x2 other)→ Float64x2

Division operator.

operator ==(Object other)→ bool

The equality operator.

inherited

operator unary-()→ Float64x2

Negate operator.
