svfloat16_t svcvtnt_f16[_f32]_m(svfloat16_t even, svbool_t pg, svfloat32_t op)

128-bit SVE

Convert each 32-bit float from (1) to a 16-bit float, writing the results to the odd lanes of (3), preserving the even lanes from (2). The current rounding mode selected by FPCR is used.

256-bit SVE

Convert each 32-bit float from (1) to a 16-bit float, writing the results to the odd lanes of (3), preserving the even lanes from (2). The current rounding mode selected by FPCR is used.

512-bit SVE

Convert each 32-bit float from (1) to a 16-bit float, writing the results to the odd lanes of (3), preserving the even lanes from (2). The current rounding mode selected by FPCR is used.
