Difference Between Float and Double

In this post, we will understand the difference between float and double data types.

float

• It has a single precision.

• It takes 4 bytes of memory.

• According to IEEE, it has 32-bit precision.

• It is used with graphic based libraries.

• It improves the processing power of programs.

• It is simple to manage by compilers.

• Its value can be between 1.2E-38 to 3.4E+38.

• It can have a precision of up to 6 decimal places.

double

• It has a double precision.

• It takes 8 bytes of memory.

• According to IEEE, it has 64-bit precision.

• Its value can be between 2.3E-308 to 1.7E+308.

• It can have a precision of up to 15 decimal places.

• It is considered as the most commonly used data type.
