the VFP coprocessor is in flush-to-zero mode

the VFP coprocessor is in default NaN mode

all exception enable bits are cleared to 0.

processes subnormal input operands as zeros

processes results that are tiny before rounding, that is, between the positive and negative minimum normal values for the destination precision, as zeros

processes input NaNs as default NaNs

returns the default result specified by the IEEE 754 standard for overflow, division by zero, invalid operation, or inexact operation conditions fully in hardware and without additional latency.
