The above fits reasonably well with Minor 19 and follows the
pattern shown by `addpcis`, which uses an entire column of Minor 19
-XO. 15 bits of FI fit into bits 11 to 25,
+XO. 15 bits of FI fit into bits 11 to 25,
the top bit FI0 (MSB0 numbered 0) makes 16.
bf16 = FI0 || FI
fp32 = bf16 || [0]*16
FRT = Single_to_Double(fp32)
+Also worth noting, `fmvis` fits well with DX-Form:
+
+| 0-5 | 6-10 | 11-15 | 16-25 | 26-30 | 31 |
+|--------|------|-------|-------|-------|-----|
+| Major | FRT | d0 | d1 | XO | d2 |
+
+ bf16 = d2 || d1 || d0
+ fp32 = bf16 || [0]*16
+ FRT = Single_to_Double(fp32)
