Reversing Integers

[vbgirl1420]

Is there a command which will reverse the order of an integer? For example, if x%=12345, I would like a command to switch x% to 54321. I also tried converting the integer to a string and reversing it, but I cannot find a way to convert the string back to an integer. Thanks in advance.

If you already converted the number to a string and reversed the digits, then use the VAL function to convert the new string to a numeric value.

Example:
NEWVALUE = VAL(NEWSTRING$)

Perhaps you can also use STR$(number%) to convert a number to a string. You should use LTRIM$ to eliminate the space before a positive number like this:

num$ = LTRIM$(STR$(number))

Then use MID$ to rearrange each letter in the number in a counter loop.

To convert a string to a number use VAL as already shown. VAL only works for string numbers, spaces and a period for decimal values. Letters will stop the value returned when encountered. DO NOT use Commas as QB does not use them! IE: 100000 instead of 100,000.

Ted is right. Before using a VAL function you should validate the string numbers. The same holds true for using the STR$ function. In general, you should always validate user input that is supposed to be strictly numeric.
