Real - GCSE Computer Science Definition

Reviewed by: Robert Hampton

Published

In GCSE Computer Science, the term 'Real' refers to a type of data that includes any number that can have a decimal point. Unlike integers, which are whole numbers, real numbers can be fractions or have many digits after the decimal point, like 3.14 or 5.678. Real numbers are important when calculations need more precision and can't be represented as simple whole numbers. They allow computers to handle everyday measurements and precise values in scientific calculations, making them essential for processing detailed data.
