Conversion Equations
Command 4 Type, Form, and Restrictions
Command 4 conversion equations have certain calculation limitations. In
particular, some conversion equations cannot perform calculations for nega-
tive values.
If a division by zero, power of a negative number, or other such error is en-
countered by an equation, an overflow value is automatically applied to the
operation.
