Get the 2.0 SDK as well if you need it. Apparently your book uses the OLD
STYLE SDK, which has slightly different type names. Place it in the Palm
include dirs and make a symbolic link to it instead of to the 3.5 SDK.

You can't. PalmOS simply doesn't support it, as I found out while trying
to write a calculator app of my own (before discovering EasyCalc).
PalmOS's support for float output is somewhat problematic... in fact one
of the things I tried to do was actually get a copy of the old glibc (a
1.x version) and adapt the code to sprintf to do it.
Oh, and while you're at it, go get a copy of the source code for mathlib.
It ought to make life easier.
And by the way, I've stopped palm dev indefinitely because my old palm
IIIe was stolen. :(
