128-bit float32 source vector |
Performs a typecast operation from 128-bit single-precision floating point values to 256-bit single-precision floating point values.
The lower 128 bits of the 256-bit resulting vector contains the source vector values; the upper 128 bits of the resulting vector are undefined. This intrinsic does not introduce extra moves to the generated code.
A vector with 256-bit single-precision floating point values. The upper bits of the resulting vector are undefined.
