Question

In what way float initialisation is different from double type initialisation?

Answer 1

1. A float type variable is initialised with a fractional value as 0.0L whereas, a double type variable is initialised with a fractional value as 0.0D. The difference between initialisations is the suffix, i.e., L and D respectively. 
2. For example, 
   float f = 0.0F;
   double d = 0.0D;
