Integers

ColdFusion supports integers between -2,147,483,648 and 2,147,483,647 (32-bit signed integers). You can assign a value outside this range to a variable, but ColdFusion initially stores the number as a string. If you use it in an arithmetic expression, ColdFusion converts it into a floating point value, preserving its value, but losing precision as the following example shows:

<cfset mybignum=12345678901234567890>
<cfset mybignumtimes10=(mybignum * 10)>
<cfoutput>mybignum is: #mybignum#</cfoutput><br>
<cfoutput>mybignumtimes10 is: #mybignumtimes10# </cfoutput><br>

This example generates the following output:

mybignum is: 12345678901234567890
mybignumtimes10 is: 1.23456789012E+020

But unfortunately this doesn't work for all functions.

eg both of following lines fail with above example:

<cfset tmp = mybignumtimes10 MOD 10>
<cfset hex = FormatBaseN(mybignumtimes10,16)>
