 New Comment:

Floating point values have a limited precision. Hence a value might 
not have the same string representation after any processing. That also
includes writing a floating point value in your script and directly 
printing it without any mathematical operations.

If you would like to know more about "floats" and what IEEE
754 is, read this:

Thank you for your interest in PHP.

Description:
------------
Using the number_format function with largue numbers, the value returned is the real + 1

Test script:
---------------
number_format(9999999999999999999, 0, '', '.')

Expected result:
----------------
9.999.999.999.999.999.999

Actual result:
--------------
10.000.000.000.000.000.000
