That's correct! In programming and mathematics, a constant is a value that remains unchanged throughout the execution of a program or within a mathematical equation. Constants are used to represent fixed values, allowing for clarity and preventing accidental alterations.
For example, in programming, you might define a constant like this:
PI = 3.14159
Here, the constant PI
represents the fixed value of pi, and you wouldn't change it elsewhere in the code.
In mathematics, constants can refer to numbers like 3
, -5
, or specific symbols like e
(the base of the natural logarithm) or π
. They serve as unchanging values in equations and formulas.
Using constants helps improve code readability and maintainability, as well as making mathematical expressions easier to understand.
