Description:
The two’s-complement quadword operand in register Fb is converted to a single- or dou-
ble-precision floating result and written to register Fc. The conversion complements a number
if negative, normalizes it, rounds to the target precision, and packs the result with an appropri-
ate sign and exponent field. Register Fa must be F31.
