Suppress the <MAXNUMBER> error on numeric overflow.


[Miscellaneous]    TruncateOverflow=n

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



This parameter has been retained for compatibility, but should not be used when building new applications.

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 Extremely Large Numbers.

Changing This Parameter

On the Compatibility page of the Management Portal (System Administration > Configuration > Additional Settings > Compatibility), in the TruncateOverflow row, click Edit. Select TruncateOverflow to enable this setting.

Instead of using the Management Portal, you can change TruncateOverflow in the Config.MiscellanousOpens in a new tab class (as described in the class reference) or by editing the CPF with a text editor

To change this parameter for a single process only (as opposed to instance-wide), use the TruncateOverflow()Opens in a new tab method of the %SYSTEM.ProcessOpens in a new tab class. See the class reference for details.
