Float64x2 class abstract final

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 implement Float64x2.


Float64x2(double x, double y)
Float64x2.fromFloat32x4(Float32x4 v)
Uses the "x" and "y" lanes from v.
Float64x2.splat(double v)


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.
no setter


abs() Float64x2
Returns the lane-wise absolute value of this Float64x2.
clamp(Float64x2 lowerLimit, Float64x2 upperLimit) Float64x2
Lane-wise clamp this to be in the range lowerLimit-upperLimit.
max(Float64x2 other) Float64x2
Returns the lane-wise maximum value in this or other.
min(Float64x2 other) Float64x2
Returns the lane-wise minimum value in this or other.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
scale(double s) Float64x2
Returns a copy of this each lane being scaled by s. Equivalent to this * new Float64x2.splat(s)
sqrt() Float64x2
Returns the lane-wise square root of this.
toString() String
A string representation of this object.
withX(double x) Float64x2
Returns a new Float64x2 copied from this with a new x value.
withY(double y) Float64x2
Returns a new Float64x2 copied from this with a new y value.
