However, if you can see through its core, know the basics, and know how to search for helps or reference, it will be getting easier.

Floating-point Note on Operators in Perl

2010-04-09T13:35:00.000+09:00

On exponentiation, don't take the number too big like: 10 ** 99999 ... otherwise, u will get unexpected result or 1.#INF The remainder operator doesn't apply for floating-point number, but if you do then they all will be round-off into the closest integers, then apply the operator.

Floating-point Round-off error

2010-04-09T01:09:00.000+09:00

In Perl, the floating-point number can be written in the form like this: 1E+01, 23.45e-02, 8.567E+32 ... The letter 'E' or 'e' denotes the exponent. Here the case: my $var_1 = 11E+30; my $var_2 = 11e30; my $small_number = 0.00001; # or 1e-05 print "First case: $var_1 - $var_2 + $small_number = ".($var_1 - $var_2 + $small_number)."\n"; print "Second case: $var_1 + $small_number - $var_2 = ".($

Here is the definition: IF (exp) { (statement) } Try this example: $age = 23; if ( $age == 23 ) { print "I am 23 years-old", '\n' } Certainly perl evaluates the expression is TRUE since $age is assigned to the value '23'. How about this case: if ( $age = 23 ) { print "I am 23 years-old", '\n' } Still you've got the result printed. But how
