What is a unary operation?
In mathematics, unary operations are functions having only one number for an input. These include functions such as finding squares, square roots, and reciprocals for a number.
What is unary mening?
'not' for instance is a unary operator. It is unary in the sense that it operates on a single item. In contrast a binary operator such as addition operates on two items.
Unary relationship in database?
Unary RelationshipsUnary relationships have only one participant-the relation is associated with itself. The classic example of a unary relationship is Employee to Manager. One's manager is, in most cases, also an employee with a manager of his or her own.
What is the difference between a positional number system and unary numerical system?
In a unary numerical system, there is only one digit: 1. Any number larger than one is represented by the symbol 1 repeated the appropriate number of times. For example, 7 (decimal) = 1111111 (unary). It is the simplest numerical system to learn but becomes quite unmanageable. Using a 10 point font the biggest number that you could write on a normal page is approx 3584: the exact value depends on the margins. At that rate you would need approximately 5 billion (yes, BILLION) pages to write out the value of the US debt (in June 2014)! And the cost of all that paper will send it up some more!By contrast, a positional system uses a base band b different digits. The place value of the digit immediately to the left of the "decimal" point is b0 = 1, the place value of the digit to its left is b1, then to its left is b2 and so on.In the decimal system, the US debt is approx USD 17530000000000. It took only(!) 14 digits to write it out. In the hexadecimal (base 16) system, the same number can be represented by USD 414DE9280, requiring only 9 digits.

What is difference between binary and unary operator in c language?
The number of arguments will be one for the unary operators and two for the binary operators. In the case of unary operators, the argument must be of the same type as that of the enclosing class or structure.
How many arguments are required in the definition of an overloaded unary operator?
any number of arguments

What is plus operator is it unary or binary?
There is no unary plus in C, but if there were, it would have only one operand, unlike the binary plus which has two: x = a + b; /* binary plus */ x = + b; /* unary plus -- not in C*/ x = a - b; /* unary plus */ x = - b; /* unary minus */
Give me the answer Difference between unary and binary operator?
A unary operator is one which operates on just one number, e.g. x2 or -x. A binary operator is one which takes two numbers, e.g. x + y or xy. Note that this has nothing to do with binary vs. decimal arithmetic. This term is commonly used to distinguish between the two buttons which have a '-' sign on a calculator. The unary '-' operator button is used to change the sign of a number entered, and the binary '-' operator button is used to subtract two numbers, which is quite a different thing. The unary '-' button is commonly labelled '+/-'.
Different operations done using rdbms?
different rdbms operations are delete,update easily and other u find on some other site. •Insert : unary operation •Delete : unary operation •Update : unary operation •Select : unary operation •Project : unary operation •Join : binary operation •Union : binary operation •Intersection : binary operation •Difference : binary operation
What is unary minus operator?
No. The subtraction operator is a binary operator that returns the result of subtracting the rhs operand from the lhs operand. The unary minus operator simply negates the rhs operand. int x = -5; // unary minus. x is (-5) int y = -x; // unary minus. y is (+5) y -= x; // binary minus/assign operator. y is (+10) --x; // unary decrement operator. x is (-6) y -= (-x); // binary minus/assign and unary minus operators. y is(+4)
What is the difference between unary and binary?
In programming a unary and binary operator defines how many components make up an expression.
Does a unary expression consists of only one operand with no operator?
No, a unary expression consists of one operand and one operator
What is unary notation?
Unary or base one notation is also called tally notation-- it uses only one digit, say 1, and the number of 1's represents the number. In this notation, 1 in one 11 is two 111 is three 1111 is four 11111 is five 111111 is six and so on.
