# Integer vs. Double: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 14, 2024
An integer is a whole number without a fractional part, while a double represents a number with decimal points, allowing for fractional values.

## Key Differences

Integers are numerical values without decimal points, representing whole numbers either positive or negative, including zero. Conversely, a double is a data type in programming that represents floating-point numbers, capable of storing large numbers with fractional parts. This distinction highlights the precision and range differences between these two numerical representations.

In terms of memory usage, an integer typically requires less storage space compared to a double. This is because integers represent a narrower range of values, whereas doubles, with their ability to hold decimals, need more memory to maintain precision. In programming, choosing between an integer and a double often depends on the nature of the data being handled.

When performing arithmetic operations, integers and doubles behave differently. Calculations with integers result in whole numbers, whereas operations with doubles can produce results with decimal points. This difference is crucial in programming and mathematical computations where precision is key.

In many programming languages, the concept of type conversion is essential when dealing with integers and doubles. An integer can be converted to a double, usually without loss of information, while converting a double to an integer involves truncating the decimal part, which can lead to loss of precision.

The representation of integers and doubles in different programming languages varies in terms of their range and precision. For instance, in some languages, an integer might be limited to a certain range of values, while a double can represent much larger or smaller numbers, albeit with a risk of precision loss for very large values.
