RE: Single line if statement with a continue

I happen to be of two schools here. Is something sort of taboo when using something like a computer language to write a program? What if another language tells you to do it a different way or sort of the opposite? Is it based on the details of the language and implementation or the prejudices o

As often seems to happen, someone asks something that may not be fully clear and others chime in and extend the question. Was the original question how to read in a ingle column of numbers from a file that are all numeric and NOT integers and be able to use them? If so, the answer was quite tri

Thanks to all! It was the rounding rounding error that I needed to avoid (as Peter J. Holzer suggested). The use of decimal solved it and just in time. I was about to truncate the number, get each of the characters from the string mantissa, and then do something like this: 64550.727 64550 + (7
