data sizes in Keil RV ARM C compiler

Hi,
I am trying to use  RV ARM C compiler from Keil and wanted to know the
data sizes and storage types used in int, char, float, etc. I saw the
following online help on keil.com but could not find the information:

RealView Compiler User's Guide
http://www.keil.com/support/man/docs/armcc/
RealView Compiler Reference Guide
http://www.keil.com/support/man/docs/armccref/

Can anyone tell where can I find this information? May be I missed it
on Keil.com website!

Thanks in advance
JS

Those characteristics are all spelled out in float.h and limits.h.

Thanks Paul. You hit the nail on the head. Thanks to others for useful
information. I will look into the header files as suggested.

I wonder if there are pdf files for Keil ARM compiler users guide and
reference.

cheers

The Keil and RealView compilers are pretty much the same with minimal
changes to features and command-line syntax.

The details of the types, size, alignment and data layout etc is in the ARM EABI.
The sizes are as you expect on any 32-bit system, so there are no surprises.
