What is the difference between FLOAT and DOUBLE?

by

FLOAT stores floating-point numbers with accuracy up to 8 places and allocate 4 bytes. On the other hand, DOUBLE stores floating-point numbers with accuracy up to 18 places and allocates 8 bytes.

In MySQL, FLOAT and DOUBLE are both data types used for storing floating-point numbers. The primary difference between them lies in their storage size and precision.

FLOAT typically requires 4 bytes of storage and offers single-precision floating-point numbers, which can store approximate values with up to 7 significant digits.

DOUBLE, on the other hand, typically requires 8 bytes of storage and offers double-precision floating-point numbers, allowing for higher precision with up to 15 significant digits.

So, in summary:

  • Use FLOAT when you need to conserve storage space or don’t require high precision.
  • Use DOUBLE when you need higher precision for your floating-point numbers.
