Quick Sum Calculator
This online calculator sums up entered numbers. Any symbol what is not a digit, for example, a space, a comma, a semicolon, etc, serves as a separator. It is useful when you need to sum up several numbers but do not have speadsheet program at hand. Use the dot symbol as separator for the decimal part of the number if you need to.
It happened that I came across a set of numbers and wanted to sum them up. So, I've created this calculator - you just drop numbers in there, then press the Calculate button and get the resulting sum. I think it is a bit more useful than the standard windows calculator since you can easily tweak numbers in the list and recalculate the sum. Also, you do not need to open a spreadsheet program and enter numbers (you don't even need to have a spreadsheet program). And, finally, it accepts any non-digit (well, except minus sign, plus sign and the dot) as the numbers separator.
