Can we assign int value to float?

Yes, an integral value can be added to a float value. The basic math operations ( + , – , * , / ), when given an operand of type float and int , the int is converted to float first. So 15.0f + 2 will convert 2 to float (i.e. to 2.0f ) and the result is 17.0f .

What is float in C++ with example?

C, C++, C# and many other programming languages recognize float as a data type.

How do you set precision in C++?
