DIVIDE

Quick Reference

Syntax

DIVIDE dobj1 BY dobj2.

Effect

This statement has the same effect as the statement

dobj1 = dobj1 / dobj2.

The content of dobj1 is divided by the content of dobj2 and the result is assigned to dobj1. The data objects dobj1 and dobj2 have to be numeric. Only data objects can be specified, no calls or other expressions. The calculation type is determined like an arithmetic expression.

Programming Guidelines

• Preventing Division by Zero
  
  
• Use the operator format
  

Notes

• Division by the value 0 is undefined and raises a handleable exception. The only situation where division by 0 does not raise an exception is if the dividend is also 0. Here, the result is set to 0.
  
  
• One obsolete form of the statement DIVIDE is DIVIDE-CORRESPONDING.
