Double and float

Question

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...

Answer 1

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

Answer 2

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
