>= is the comparison operator that means greater than or equal to.
Yes
<=
"≠" is used in mathematics, though because of the limitations of the Ascii character set then != is often used in programming. In Microsoft Excel, the comparison operator that means "not equal to" is either NOT, or <>.
Yes.
It is any of the operators used to compare things to see if they are equal or greater than to less than etc. So ones like > < = are all comparison operators.
You can use the Not function or the <> operator, which is the < and the > beside each other. To see if the values in A1 and A2 are not equal to each other, you can type: =A1<>A2 or =Not(A1=A2) In each case they will either give you TRUE if they are not equal or FALSE if they are equal, in the cell that you enter the formula into.
If the "comparison symbol" is the equal sign, it is called an "equation". If the symbol is less than, greater than, less-than-or-equal, or greater-than-or-equal, it's called an "inequality".
Comparison
One possible way (although much less efficient than using the operators directly) is by using BigInteger: int a = 5, b = 7; int sum = BigInteger.valueOf(a).add(BigInteger.valueOf(b)).intValue(); However, BigInteger.add() might use arithmetic operators in its own calculations; they are simply hidden from the programmer's view.
Less than (<) Greater than (>) Equal to (=) Greater than or equal to (> but it has another horizontal line under it) Less than or equal to (< but it has another horizontal line under it) Not Equal to (= but with a / through it)
Conditional operators are used to compare two values. The result of a comparison is either true or false. Boolean data types can hold the values true or false. Here's a list of operators. = Equal to > Greater than < Less than >= Grater than or equal to <= Less than or equal to <> Not equal to
