J2ME: Dealing with Floating Points?

gilgantic

How do you deal with floating points in J2ME? From my understanding
MIDP 1.0 does not allow you to use float or double primitives. I want
to be able to perform a calculations which give float or double
values.

Thanks

Hi.

J2ME (CLDC1.0) does not have support for floats/doubles. Do a 'google' on
"fixed point J2ME" and you'll find some free libraries that implement fixed
point numbers. The ones i've found are mainly used for games, where
precision is of a lower priority than speed. I've written (using the
BigDecimal class from J2SE as a basis), for a program that i'm writing, a
library handling fixed point values with arbitray precision for J2ME. It is
very precise but not very fast.

Yes you are right you cannot use floating point primitives in J2ME. How
ever there is a working around to solve this problem. Try to look at

Hi, Is there any way that I can scroll a canvas - i.e. if there are too many items on the canvas you can still access by pressing down. I know Form does this (apparently) but I need to do it using a canvas!. Maybe I can attach my Canvas to a form? Ideas? Oz.

Anyone using J2ME in non-commercial applications?

We are looking at using J2ME in a embedded device that will be deployed in an industrial application and I've been doing some research to see how practical J2ME would be for our application. Most of the devices I've come across that use J2ME are consumer devices like phones and PDAs. I would be interested in hearing from anyone who might be using J2ME on devices other than consumer type devices. What kind of processor are you using? ...

/CLR floating point performance, inter-assembly function call performance

by: Bern McCarty | last post by:

I have run an experiment to try to learn some things about floating point performance in managed C++. I am using Visual Studio 2003. I was hoping to get a feel for whether or not it would make sense to punch out from managed code to native code (I was using IJW) in order to do some amount of floating point work and, if so, what that certain amount of floating point work was approximately. To attempt to do this I made a program that...

Beware CS1612 when dealing with "Point" (it's not really a structurelike most of us think of)

by: raylopez99 | last post by:

I ran afoul of this Compiler error CS1612 recently, when trying to modify a Point, which I had made have a property. It's pointless to do this (initially it will compile, but you'll run into problems later). Apparently Point is a struct, a value type, and it does not behave like a classic structure (in my mind's eye, and see below). Traditionally I think of a classic structure as simply an object where every member is public. But with...
