TruncateOverflow

Suppress the <MAXNUMBER> error on numeric overflow.

Synopsis

[Miscellaneous]    TruncateOverflow=n

n is either 1 (true) or 0 (false). The default value is 0.

Description

Normally, when InterSystems IRIS® data platform encounters an extremely large number (on the order of 1.0E147, or -1.0E146), it throws the <MAXNUMBER> error. When TruncateOverflow is enabled, the <MAXNUMBER> error is suppressed.

For more information, see the Extremely Large Numbers section of the “Data Types and Values” chapter in Using ObjectScript.
