What is the difference between float and double?

The primary difference between float and double in C (and other languages) lies in their precision and storage size.

1. Size:
   • float: Typically occupies 4 bytes (32 bits) of memory.
   • double: Typically occupies 8 bytes (64 bits) of memory.
2. Precision:
   • float: Has a precision of about 6–7 decimal digits.
   • double: Offers higher precision with approximately 15–16 decimal digits.
3. Range:
   • double can represent a larger range of values than float, making it suitable for calculations requiring more precision or a wider range.

For higher precision, double is preferred, but it consumes more memory.
