int() function in Perl returns the integer part of given value. It returns $_ if no value provided. Note that $_ is default input which is 0 in this case. The int() function does not do rounding. For rounding up a value to an integer, sprintf is used.
Syntax: int(VAR)
Parameters:
VAR: value which is to be converted into integer
Returns: Returns the integer part of VAR
Example 1:
$int_val = int (19.8547);
print "Integer value is $int_val\n" ;
$int_val = int (-18.659);
print "Integer value is $int_val\n" ;
|
Output:
Integer value is 19
Integer value is -18
Example 2:
$int_val = int (17 / 4);
print "Integer value is $int_val\n" ;
$int_val = int (-17 / 4);
print "Integer value is $int_val\n" ;
|
Output:
Integer value is 4
Integer value is -4
