int32x4
struct int32x4Available without an import.
A 128-bit SIMD value containing 4 int32 lanes. Arithmetic operates lane-wise, with integer overflow wrapping within each lane. Lane and WithLane require constant indices; bracket indexing supports checked runtime indices. Comparisons return all-one/all-zero integer masks. Bit reinterpretation involving floating-point lanes canonicalizes NaNs.
Members
Splatmethod
public static fn Splat(int32 value) : int32x4Copies one scalar value into every lane.
Zeromethod
public static fn Zero() : int32x4Returns a vector whose lanes are all zero.
constructorconstructor
public constructor (int32 l0, int32 l1, int32 l2, int32 l3)Creates a vector from scalar lanes in ascending index order.
Lanemethod
public fn Lane(int32 index) : int32Reads a compile-time constant lane index in [0, 4). Invalid or nonconstant indices are rejected; use bracket indexing for runtime indices.
ReduceSummethod
public fn ReduceSum() : int32Sums every lane into the scalar result. Arithmetic wraps at the scalar result width; narrow lanes are widened before addition.
ReduceMinmethod
public fn ReduceMin() : int32Reduces all lanes to their minimum.
ReduceMaxmethod
public fn ReduceMax() : int32Reduces all lanes to their maximum.
Minmethod
public fn Min(int32x4 other) : int32x4Selects the smaller value in each lane.
Maxmethod
public fn Max(int32x4 other) : int32x4Selects the larger value in each lane.
Absmethod
public fn Abs() : int32x4Returns each lane's magnitude. A minimum signed lane remains the negative minimum because its positive magnitude does not fit.
Eqmethod
public fn Eq(int32x4 other) : int32x4Compares corresponding lanes for equal, returning all-one bits for true and all-zero bits for false. Ordered comparisons use the lane type's signedness.
Nemethod
public fn Ne(int32x4 other) : int32x4Compares corresponding lanes for unequal, returning all-one bits for true and all-zero bits for false. Ordered comparisons use the lane type's signedness.
Ltmethod
public fn Lt(int32x4 other) : int32x4Compares corresponding lanes for less, returning all-one bits for true and all-zero bits for false. Ordered comparisons use the lane type's signedness.
Lemethod
public fn Le(int32x4 other) : int32x4Compares corresponding lanes for less or equal, returning all-one bits for true and all-zero bits for false. Ordered comparisons use the lane type's signedness.
Gtmethod
public fn Gt(int32x4 other) : int32x4Compares corresponding lanes for greater, returning all-one bits for true and all-zero bits for false. Ordered comparisons use the lane type's signedness.
Gemethod
public fn Ge(int32x4 other) : int32x4Compares corresponding lanes for greater or equal, returning all-one bits for true and all-zero bits for false. Ordered comparisons use the lane type's signedness.
AnyTruemethod
public fn AnyTrue() : boolTests whether any lane has a nonzero bit pattern.
AllTruemethod
public fn AllTrue() : boolTests whether every lane has a nonzero bit pattern.
Bitmaskmethod
public fn Bitmask() : int32Packs each lane's most significant bit into the corresponding bit of an integer; lane zero becomes bit zero.
WithLanemethod
public fn WithLane(int32 index, int32 value) : int32x4Returns a copy with one lane replaced. The index must be a compile-time constant in [0, 4); use bracket assignment for runtime indices.
Shufflemethod
public fn Shuffle(int32 l0, int32 l1, int32 l2, int32 l3) : int32x4Returns lanes selected in argument order. Every index must be a compile-time constant in [0, 4); repeats are allowed.
Selectmethod
public fn Select(int32x4 a, int32x4 b) : int32x4Selects bits from a where this mask has one bits and from b where it has zero bits. Comparison masks select entire lanes; arbitrary masks can mix bits within a lane.
Blendmethod
public fn Blend(float32x4 a, float32x4 b) : float32x4Selects floating-point bits from a where this integer mask has one bits and from b where it has zero bits. Comparison masks select entire lanes.
WidenLowmethod
public fn WidenLow() : int64x2Widens the low half of the lanes to twice their width, using sign extension.
WidenHighmethod
public fn WidenHigh() : int64x2Widens the high half of the lanes to twice their width, using sign extension.
WideningMulLowmethod
public fn WideningMulLow(int32x4 other) : int64x2Multiplies the low-half lane pairs, widening operands first so products fit the doubled lane width.
WideningMulHighmethod
public fn WideningMulHigh(int32x4 other) : int64x2Multiplies the high-half lane pairs, widening operands first so products fit the doubled lane width.
Narrowmethod
public fn Narrow(int32x4 other) : int16x8Saturates both vectors into half-width lanes. Receiver lanes form the low half and other lanes the high half; values clamp to the destination range.
