Perl | int() function

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: Perl

#!/usr/bin/perl

# Passing positive decimal value
$int_val = int(19.8547);
print"Integer value is $int_val\n";

# Passing negative decimal value
$int_val = int(-18.659);
print"Integer value is $int_val\n";

Output:

Integer value is 19
Integer value is -18

Example 2: Perl

#!/usr/bin/perl

# Passing fractional positive value
$int_val = int(17 / 4);
print"Integer value is $int_val\n";

# Passing fractional negative value
$int_val = int(-17 / 4);
print"Integer value is $int_val\n";

Output:

Integer value is 4
Integer value is -4
