Error,  (in ...) numeric exception: division by zero

 

Description

Examples

Description

In Maple, dividing by zero produces a division by zero error. However, sometimes the division by zero is not apparent.

Examples

Example 1

Error, (in ln) numeric exception: division by zero

Error, (in tan) numeric exception: division by zero

Solution: Replace the NumericEventHandler for division by zero.

(2.1)

(2.2)

(2.3)

Example 2

(2.4)

(2.5)

Error, (in simplify/trig) numeric exception: division by zero

The weakness is in int, which does not identify  as equal to 0.  Simplifying the expanded output from int then leads to division by zero. A stronger zero-testing routine is required earlier in the process. However, using the strongest possible zero-testing routine by default is inefficient.

Solution 1: For a single expression, simplify before taking the integral.

(2.7)

Solution 2: For numerous expressions, control zero-testing using Normalizer.

(2.9)

(2.10)
