Compute Operations
Syntax:
Fn = RND Fx
Function:
Rounds the floating-point operand in register Fx to a 32 bit boundary.
Rounding is to nearest (IEEE) or by truncation, as defined by the rounding
mode bit in MODE1. Post-rounded overflow returns ±Infinity (round-to-
nearest) or ±NORM.MAX (round-to-zero). A denormal input is flushed to
±Zero. A NAN input returns an all 1s result.
Status flags:
Is set if the result operand is a ±Zero, otherwise cleared
AZ
AU Is cleared
AN Is set if the floating-point result is negative, otherwise cleared
AV Is set if the post-rounded result overflows
(unbiased exponent > +127), otherwise cleared
AC Is cleared
AS Is cleared
AI Is set if the input operand is a NAN, otherwise cleared
