The ROUNDED Phrase

If, after decimal point alignment, the number of places in the fraction of the result of an arithmetic operation is greater than the number of places provided for the fraction of the resultant-identifier, truncation is relative to the size provided for the resultant-identifier. When rounding is requested, the absolute value of the resultant-identifier is increased by one whenever the most significant digit of the excess is greater than or equal to five.

When the low-order integer positions in a resultant-identifier are represented by the character "P" in the PICTURE for the resultant-identifier, rounding or truncation occurs relative to the rightmost integer position for which storage is allocated.
