Where can I find the class and package downloads.

I lost the link for the Javalin classes and packages.
Specifically I need to do some "floating point" math for scaling my inputs and unit conversion.
Does anyone know where I can download such?

My input values are in the range of 0 to 1023 (tem bit). I need to mulitiply it by 1.48
I tried to multiply by 148 and divide by 100 but that does'nt work because of divide is only working on 1 word.
Is there a way to create two words with the Mult. then divide these two words by 100(so that I'm back to one word?
Maybe somthing like a Double Multiply and Double Divide in PLC programming?

The easiest way is to use the UnsignedIntMath class:
http://tech.groups.yahoo.com/group/JavelinCode/files/Javelin%20Stamp%20IDE/lib/stamp/math/

int result = value + UnsignedIntMath.umulf(value,31457); //31457 = 0.48*65536

But in this case you could do without the class

1.48 * value = value + ((12*value)/25);

For a rounded result you can use

int result·= value + ((24*value + 25)/50);
