WebThe sizeof () operator is a function which returns the size of any data type, expression, array, etc. It takes the data type or expression as a part of argument which is mandatory and returns the result which is size of that data type in bytes. If it is an array it will return the number of elements present in it. WebMar 25, 2024 · Float data type allows a variable to store decimal values. Storage size of float data type is 4. This also varies depend upon the processor in the CPU as “int” data type. We can use up-to 6 digits after decimal using float data type. For example, 10.456789 can be stored in a variable using float data type.
