Variable not posting/storing properly.

Problem Description

A INT variable with the value of 11111... that is 16 digits in length or higher does not post properly with a string attached.

A INT variable with the value of 11111... that is larger than 16 digits doesn't store properly.

Attach a Capx

Description of Capx

Contains 4 variables of the value 1111... repeating in differing lengths 15,16,17 and 18.

Contains 4 groups with two types of displays a straight Set Text to Variable and a Set Text to a String+Variable that update every tick.

Steps to Reproduce Bug

• Create an INT variable with a value of 1111....repeating in any length greater than or equal to 16.
• Create a Text Object
• Set the text, using any type of event, to "String"&variable

Observed Result

____ The variable flop16 posts as 1111111111111111.1

____ The variable flop17 stores as 11111111111111110

____ The variable flop18 stores as 111111111111111100

Expected Result

____ The variable be posted as it is stored, and be able to store a repeating 1111.... past 17 digits in length ____

It's one of those number precision things with computers. There is a limit to the number of digits of a number can be stored. JavaScript uses 64-bit floating point numbers to store numbers and according to this:

http://en.wikipedia.org/wiki/Double-pre ... int_format

It can store 15-17 significant digits, which is on par from what you found.

Closing as not a bug, you've just discovered the double floating point precision limit.
