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
this url:

If it does't work please send me an e-mail and I will look at is.
