Mojo function

remove_neg_zero

def remove_neg_zero[dtype: DType, width: Int](v: SIMD[dtype, width]) -> SIMD[dtype, width]

Maps every -0.0 lane to +0.0, leaving all other lanes bit-identical.

This is the producer-sanitize step: after it, real data can never be mistaken for the readiness sentinel. Lanes holding +0.0, NaN, Inf, or any normal value are returned bit-for-bit unchanged. The implementation is branchless: bitcast to the unsigned lane type, select the sentinel lanes to +0.0 bits (all zero), and bitcast back.

Parameters:

dtype (DType): The transport float type. Must be bfloat16, float16, or float32.
width (Int): The SIMD pack width.

Args:

v (SIMD[dtype, width]): The pack to sanitize.

Returns:

SIMD[dtype, width]: v with any -0.0 lane replaced by +0.0.
