A number whose value, when ascertained (as by observation) and substituted in a general mathematical formula expressing an astronomical law, completely determines that law and enables predictions to be made of its effect in particular cases.
Value expressing the relation between the energy registered by the meter and the corresponding value of the test output. If this value is a number of pulses, the constant should be either pulses per kilowatt-hour (imp/kWh) or watt-hours per pulse (Wh/imp).
A data object with a value that does not change. Contrast with variable. The four classes of constants specify numbers (arithmetic), truth values (logical), character data (character), and typeless data (hexadecimal, octal, and binary).
uninterrupted in time and indefinitely long continuing; "the ceaseless thunder of surf"; "in constant pain"; "night and day we live with the incessant noise of the city"; "the never-ending search for happiness"; "the perpetual struggle to maintain standards in a democracy"; "man's unceasing warfare with drought and isolation"; "unremitting demands of hunger"
A value which is set at design time, which cannot be changed during program execution. It may be use for things such as the number of feet in a mile, to make your code more readable. Back to where you were
(n.) a data object whose value must not change during execution of an executable program. In Fortran 90 it may be a named constant or a literal constant, whereas in Fortran 77 a constant may only be a literal constant.
any fundamental value (either with units or dimensionless) inherent to the Universe; the fundamental physical constants include the speed of light c, Planck's constant h, the gravitational constant G, Boltzmann's constant k, the gas constant R, and many others
A named item that retains a constant value throughout the execution of a program. Constants can be used anywhere in your code in place of actual values. A constant can be a string or numeric literal, another constant, or any combination that includes arithmetic or logical operators except Is and exponentiation. For example: Const A = "MyString"
A constant is a variable that will never change. By using the keyword final, a variable can be assigned to only once. (This is usually done when the variable is declared, but not nexessarily.) Most constants are declared as being final and static, which makes them available without an instance of the class that contains them, but this is not required. The keyword final is really what makes a variable a constant.
In programming circles, a constant is a value that doesn't change. Constants are very similar to variables because both use a name to refer to a memory location that holds a value. The exception is that, with constants, that value can't change; with variables, it can. Normally, trying to change a constant would generate a compile-time error. Unfortunately, Perl does not have true constants, but you can emulate them by initializing a variable and then never assigning a second value to it. Some programmers like to emulate constants by using a function to return a value. This works, but it is very, very slow.
The constants in an experiment are all the factors that do not change. These will vary depending on what question is being addressed. In a bioassay experiment, usually the temperature is kept constant. However, if the question being investigated were, "How does temperature affect lettuce seed germination and growth?" then in this case the temperature would be a variable rather than a constant.
1. an item with a fixed value or something which does not change. For example, in Lingo, TRUE is a constant that always equals one (1), and FALSE is a constant that always equals zero (0). See dynamic, static, Death and Taxes.
A data object whose value does not change during the execution of a program; the value is defined at the time of compilation. A constant can be named (using the PARAMETER attribute or statement) or unnamed. An unnamed constant is called a literal constant. The value of a constant can be numeric or logical, or it can be a character string. Contrast with variable.
A constant is a value which never changes, regardless of circumstances. One example of a constant in a formula is the number 3: The number 3 will never become a different value. Constants are in contrast to variables, which can change their values.
WATTAGE AUTOTRANSFORMER (CWA) BALLAST: A popular type of HID ballast in which the primary and secondary coils are electrically connected. Considered an appropriate balance between cost and performance.
The constant â€œcâ€ can be set and is required by the tachograph to display speed or rpm correctly. On the DTCO it is adjusted to the vehicleâ€(tm)s distance pulse count with the aid of approved service diagnostic systems.
