Kindly refer the images and the sentences below them.
If an integer/float is entered, then it shows its absolute value, which is normal.
If a “string” is entered, then it shows 'Not Applicable…". It is also normal.
If anything else is entered, then the desired ‘else’ command doesn’t work. Why? Another example in the below image.
Note: I am a beginner. This can be a stupid question. Kindly help.
