Double and float

void Test(double d) {cout << "1";} void Test(float e) {cout << "2";} int main() { Test(1.0); // calls double function } I am not aware how to call Test from main for float... I mean to say what should be passed as value for float type function call...

the compiler takes in double as default. Its good practice to specify floats as 2.03f with the f at the end of the number

Man Ketan Lalcheta you can use float casting to if you are sure about calling function is passing float data. Test((float)1.0); // calls float function

its better practice to forget about float and always use double. Internally java casts every float to a double and then converts them back anyway
