Known Subclasses:

• Overflow
• , Underflow

Number got rounded (not necessarily changed during rounding).

This occurs and signals rounded whenever the result of an operation is rounded (that is, some zero or non-zero digits were discarded from the coefficient), or if an overflow or underflow condition occurs. The result in all cases is unchanged.

The rounded signal may be tested (or trapped) to determine if a given operation (or sequence of operations) caused a loss of precision.
