Float vs. Double: Know the Difference
By Shumaila Saeed || Published on February 17, 2024
Float and Double are both data types used in programming to store decimal numbers, but Double has higher precision than Float.
Key Differences
Float and Double are both floating-point data types used in various programming languages to store numbers with fractional parts. Float is a single-precision, 32-bit floating-point data type and can store decimal numbers up to 7 decimal digits accurately. Double, short for double-precision, is a 64-bit floating-point data type with a precision of up to 15 decimal digits, making it more accurate for storing large or precise decimal numbers.

The key difference between Float and Double is their precision and storage size. Float, being a 32-bit type, occupies less space in memory compared to Double, which is a 64-bit type. This makes Float more memory-efficient, but it also means it has a smaller range and less precision than Double.

In terms of usage, Float is often used in applications where memory conservation is crucial and the exact precision of large decimal numbers is not critical. Double, with its higher precision, is preferred in calculations requiring greater accuracy, such as scientific computations and financial calculations.

The choice between Float and Double depends on the specific requirements of the application. If the application needs to handle large numbers with high precision, Double is the preferred choice. Conversely, if the application is running on a device with limited memory and does not require high precision, Float may be more suitable.

Both Float and Double are susceptible to rounding errors, but the effects are more pronounced in Float due to its lower precision. Developers need to consider these factors when choosing between Float and Double for their computational needs.
