What is the difference between float and double?

Question

I\'ve read about the difference between double precision and single precision. However, in most cases, float and double seem to be interchangeable,

Answer 1

Unlike an int (whole number), a float have a decimal point, and so can a double. But the difference between the two is that a double is twice as detailed as a float, meaning that it can have double the amount of numbers after the decimal point.
