How to make integer variable on JavaCard 2.2.2?

Postby Erisaron » Sat Dec 05, 2015 4:24 am

As far as I know, there is no integer variable on JavaCard 2.2.2. Am I right? I am developing an applet which needs int variable and four basic arithmetic operations + - * / .

I want to know how to make the int variable and process the four basic arithmetic operations. Any help? I am much appreciated!

The card need to support JCint.
For your applet compatibility, implement JCint yourself in your applet.
Currently issued cards support JCint generally, few are not support.
sense and simplicity

Just a heads up that JCMathLib also provides an Integer class. :)
