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

• A double is 64 and single precision (float) is 32 bits.
• The double has a bigger mantissa (the integer bits of the real number).
• Any inaccuracies will be smaller in the double.
