Re: (ar0n) Re: How do I get a loop to recognize a number between $i and $i+1 (a decimal number)

Aloha, Mahalo for your reply. I am just a beginner. What I am trying to write is a script to correct an online quiz. It works fine for questions that have only one value. But I'm trying to get it to recognize that some questions have more than one value (because they may have dropdown boxes) What I thought I would do was give half credit if one of the two drop down boxes were correct. kailua362

The theory behind ar0n's answer is to use integers inside your program and convert them to decimals when displaying them to the user. In general, computers tend to be far better at handling integers than floating point (decimal) numbers. See Why am I getting long decimals (eg, 19.9499999999999) instead of the numbers I should be getting (eg, 19.95)? (part of perlfaq4) for a good explanation of why that is.	[reply]
