Error Message
Cause Action
Math ERROR
• The intermediate or final
result is outside the
allowable calculation range.
• An attempt to perform a
calculation using a value
that exceeds the allowable
input range.
• An attempt to perform an
illogical operation (division
by zero, etc.)
Check the input values and
make sure they are all
within the allowable
ranges, Pay special
attention to values in any
using memory areas
