What is the difference between float and double?

The key difference between float and double in programming lies in their precision and memory usage:

1. Precision:
   • float: 32-bit (single precision), accurate up to 6-7 decimal places.
   • double: 64-bit (double precision), accurate up to 15-16 decimal places.
2. Memory:
   • float uses 4 bytes.
   • double uses 8 bytes.
3. Range:
   • float: Smaller range, suitable for less precise calculations.
   • double: Larger range, ideal for high-precision computations.

Example:

Use float for memory efficiency and double for higher accuracy.
