According to my CCS book, the sizes are as follows:

unsigned:       8 bits
unsigned int:   8 bits
int:            8 bits
char:           8 bits
long:           16 bits
long int:               16 bits
signed:         8 bits
signed int:     8 bits
signed long:    16 bits
float:          32 bits
short:          1 bit
short int:      1 bit

Hang on a millisecond..  What is the big deal over int?  A signed int should
be
+3286X to -3276X, and an unsigned int should be 0-65535.  Whenever yall
discuss
converting to -6, that applies to a char or uchar only.  The confusion comes
in
with compilers that have a short int, and or a long which is a 16 not 32 bit
variable.  So I am still puzzled as to why everyone thinks that a int
converts 250
to -6.  Someone should look on the variable types page of CCS and find out
where
they stand.

One more time:
uchar        8 bit
char        8 bit
uint        16 bit
int        16 bit
ulong    32 bit
long    32 bit
