char or signed char                -128 to 127
unsigned char                          0 to 255
int or signed int                      -32768 to 32767
unsigned int                            0 to 65536
long int                                  -2,147483,648 to + ..47
float                                        3.4e-38 to 3.4e+38
double                                    1.7e-308 to 1.7e+308
