WebAug 1, 2024 · There are three different floating point data types: float, double, and long double. As with integers, C++ does not define the actual size of these types (but it does guarantee minimum sizes). On modern architectures, floating point representation almost always follows IEEE 754 binary format. WebC++ has 3 different char types: char. signed char. unsigned char. In practice, there are basically only 2 types: signed char (guaranteed range: -127 to 127) unsigned char (guaranteed range: 0 to 256) This is because different compilers treat char as either signed char or unsigned char according to their own preference.
