## 128-bit SVE

Convert each 64-bit float from (1) to a 32-bit float, rounding to odd, writing the results to the odd lanes of (3), preserving the even lanes from (2)

## 256-bit SVE

Convert each 64-bit float from (1) to a 32-bit float, rounding to odd, writing the results to the odd lanes of (3), preserving the even lanes from (2)

## 512-bit SVE

Convert each 64-bit float from (1) to a 32-bit float, rounding to odd, writing the results to the odd lanes of (3), preserving the even lanes from (2)

## Larger sizes

## 1024-bit SVE
