Slider max

I’m selftaught in C++, so please forgive me if this is a stupid question.

In the projucer, I’m trying to set the max value of a slider to 2147483647. However, the projucer changes this to 2.14748e+09. This then sets the last 4 digits to 0.

Am I doing it wrong, or should I just change it later, and never open the project in the projucer henceforth?

Cheers!
Søren
