thanx a lot Jeff Loucks . we will try it out.

Int32 and UInt32 on Palm hold the same as a signed and unsigned 32 bit

signed 32 bit integer = -(2^31)..(2^31-1) = (2-2147483648..2147483647
unsigned 32 bit integer = 0..(2^32-1) = 0..4294967295
You probably did something like the following:
Int32 result = 370 * 370; // you expect 136900, but get 5828
The size of the left hand side of your assignment is not the problem.
We know that 370 * 370 = 136900. However, the compiler computed the
right hand side as an int, which is probably set to 2 byte (16 bits),
not 4 byte (32 bits). The 16 bit int result is missing the top 2 bits
of the result you expect. This truncated result is then placed in the
32 bit integer 'result'.
Use this, instead:
Int32 x = 370L * 370L; // right hand side is computed as a 32 bit int
You asked about larger integers. Most compilers these days understand
at least 'long long' or QWord, which is an 8 byte (64 bit) integer.
This is not a native size on Palm, but is supported in code.

Hi,
Can anyone tell us how much value Int32 and UInt32 can hold in
palm
. Is there any data type which can hold bigger than this.
for eg we were not able to hold the square of the no: 370 in UInt32 ,
long , Int32.
Waiting for ur speedy reply.
thanx
anoop
