0x800	UFE	Underflow exception enable
0x1000	IXE	Inexact exception enable
0x8000	IDE	Input denormal exception enable
0x0 (bits 23 and 24 clear)	RMode=RN	Round to nearest
0x400000	RMode=RP	Round towards plus infinity
0x800000	RMode=RM	Round towards minus infinity
0xC00000	RMode=RZ	Round towards zero
0x1000000	RMode=(per above)+FZ	Flush-to-zero
0x2000000	RMode=(per above)+DN	Operations on NaN return default NaN
0x1000000	RMode=(per above)+AHP	Alternative half-precision
