Assume variable $a holds 10 and variable $b holds 20, then following are the Perl arithmatic operators −, Adds values on either side of the operator, Subtracts right hand operand from left hand operand, Multiplies values on either side of the operator, Divides left hand operand by right hand operand, Divides left hand operand by right hand operand and returns remainder, Performs exponential (power) calculation on operators, Example − $a**$b will give 10 to the power 20, These are also called relational operators. When the above code is executed, it produces the following result −. The second parameter of split is the string to be cut in pieces.If no second parameter is given, split will cut up the content of $_. Home. Bitwise Operators 6. Assignment operators are used to assigning a value to a variable. Shifting by more bits than the size of the integers means most of the time zero all bits fall off , except that under use integer right overshifting a … Thus you can do things like $a = 5 + ($b = 6), which will set $b to a value of 6 and $ato a value of 11 (5 + 6). Perl comparison operators can sometimes be confusing to new Perl programmers.The confusion stems from the fact that Perl actually has two sets of comparison operators - one for comparing numeric values and one for comparing string American Standard Code for Information Interchange (ASCII) values. Operators are the basic building blocks of any programming language. Binary Left Shift Operator. 0.

Assignment Operators Perl recognizes the C assignment operators, as well as providing some of its own. Here 4 and 5 are called operands and + is called operator. Basically, just about any operator that has two operands has a shorthand assignment version, where the general rule is that Assume if $a = 60; and $b = 13; Now in binary format they will be as follows −, There are following Bitwise operators supported by Perl language, assume if $a = 60; and $b = 13. Assume variable $a holds true and variable $b holds false then −. **= The exponentiation assignment operator. How does the assignment operator (=) in Perl work internally? (See "Context" and "List value constructors" in perldata, and "Assigning to References" in perlref.) Returns -1, 0, or 1 depending on whether the left argument is stringwise less than, equal to, or greater than the right argument. Assignment operators perform an arithmetic operation and then assign the value to the existing variable. Add AND assignment operator, It adds right operand to the left operand and assign the result to left operand.
