Windows 7: Excel 15 digit number limit issue

Excel 15 digit number limit issue

Try this. Type a 16-digit number in a cell, say:

Then right click the cell and format this as a number, with no decimal places.
Your number has just become:
1234567890123450 (note the last digit is now a zero).

great stuff. Not. It has effectively corrupted your input (changed your value) without notifying you in any way that you've hit a limit.

My question is - is this known behaviour for Excel 2007?

Windows 7 Ultimate X64 SP1

Hi skydiver welcome to the forums. It seems this is a known limitation of Excel. See below.

Microsoft Excel supports a maximum of 15 significant digits at all times. This limit applies to a value that is calculated by a formula. Because of this limitation, if at any time a formula calculates a value that exceeds 15 digits in length, digits beyond the fifteenth significant digit are changed to zeroes. This may cause the formula to return an incorrect result.
From: Problems vith Statistical Functions and Large Numbers in Excel

Incidentally, I dont know if it helps, but Open Office Calc (which is free by the way ) doesn't have this limitation:
