Semantics
D0.f16 = sqrt(S0.f16)
Example
V_SQRT_F16(0xfc00) => 0xfe00 // sqrt(-INF) = NAN
V_SQRT_F16(0x8000) => 0x8000 // sqrt(-0.0) = -0
V_SQRT_F16(0x0000) => 0x0000 // sqrt(+0.0) = +0
V_SQRT_F16(0x4400) => 0x4000 // sqrt(+4.0) = +2.0Reproduced from AMD's official "AMD Instinct MI300" ISA Reference Guide for technical accuracy.
