Constant variables are variables that, once initialized, do not change in value. They are effectively the same as literal constants, except that you can use symbolic names to make it easier to understand the meaning of the program.
For instance, in a trigonometry program, it is easier to use the identifier PI than it is to use the literal 3.1415926535897932. Also, if you have a constant that might be adjustable, such as a factor in an equation, naming it allows you to change its value by changing only one line of code, rather than seeking out all of the lines of code that refer to the factor.
Constant variables are also candidates for being placed in read-only memory, potentially making the program more secure.

A constant that multiplies a variable?
A constant that multiplies a variable is no longer a constant. By its very definition, a constant is something that can never be different. The result of variable multiplication is thus a variable, not a constant.I would say that the above answer is not necessarily true. The common equation for the area of a circle is: area = pi * r2The fact that you are multiplying the mathematical constant pi by a variable does not change the value of pi.Agree with the second answer. Jsut to add, a constant that multplies a variable is called a coefficient.
What is the principles of digital terrain modelling?
The principles of digital terrain modelling include elevation and local topographic variables. It also includes regional topographic variables as well as structural lines.
What letter can be a vowel and a constant?
Y
What is a constant in computer?
In computer terms (especially in programming), a constant is a piece of data that has a set value which cannot be changed. For example, 1 and 3 are constants - they will always equal their respective values. Constants can also be set, so you could make: piValue a constant equal to 3.14.
When using post method in php whether the variable displayed in url?
No, the variables do not form part of the URL visible in the address bar. They only display in GET methods or manually appended.To access POST variables in scripts, you need to use $_POST['variable_name'];
What does the constant variable do?
Variables are not constants. The terms have opposite meaning.
Are constant variables and derived variables the same?
Constant variables are constant, they do not change. Derived variables are not constant. They are determined by the other values in the equation.
The variables in an experiment that stay the same?
These "variables" are called independent variables or constant variables meaning that they are capable of being changed by the experimenter but are intentionally held the same through each individual experiment.
Are constant variables and independent variables the same?
No they are not the same. A constant variable keeps going at a constant rate.
Is holding other variables constant called ceteris paribus?
Ceteris paribus does translate into meaning "all other things being equal or held constant.
What is the constant and the variables in Boyles law?
The constant k is a...constant specific for the system considered.
What is a monomial with no variables?
constant
How many variables are kept constant in a experiment?
All variables except one, the experimental variable, are kept constant in an experiment.
What are the two types of variables?
The two types of variables are the CONSTANT and CONTROL.
What are all the variables?
There are 'constant variables' , 'independant variables' and 'dependent variables' Constant Variable- things in the experimment that should be kept the same Independant variables- something that can be varied in an experiment Dependant variable- something that can be affected
What does constant mean in math?
Constant is a number with no variables. For an example, 12a, but this is a constant 12.
What are constant variables and y r they important in an experiment?
. Constant variables are variables which cannot be changed with the experiment. To remember their name is easy just think about Constance. They are important to an experiment because without all three variables there would be no complete experiment. Also the constant variables are important to an experiment because they help complete the result. Without a constant variable you. Would not be testing correctly
