`fmvis FRS, FI`
Reinterprets `FI << 16` as a 32-bit float, which is then converted to a
-64-bit float and written to `FRT`. This is equivalent to reinterpreting
+64-bit float and written to `FRS`. This is equivalent to reinterpreting
`FI` as a `BF16` and converting to 64-bit float.
There is no need for an Rc=1 variant because this is an immediate loading
instruction.
```
# these two combined instructions write 0x3f808000
# into f4 as an FP32 to be converted to an FP64.
-# actual contents in f4 will be 0x3f80_8000_0000_0000
+# actual contents in f4 after conversion: 0x3ff0_1000_0000_0000
# first the upper bits, happens to be +1.0
fmvis f4, 0x3F80 # writes +1.0 to f4
# now write the lower 16 bits of an FP32
-fishmv f4, 0x8000 # writes +1.0039063 to f4
+fishmv f4, 0x8000 # writes +1.00390625 to f4
