Repo : installed
From repo : amzn2-core
Summary : Perl pragma to declare constants
URL : http://search.cpan.org/dist/constant/
License : GPL+ or Artistic
Description : This pragma allows you to declare constants at compile-time:
:
: use constant PI => 4 * atan2(1, 1);
:
: When you declare a constant such as "PI" using the method shown
: above, each machine your script runs upon can have as many digits
: of accuracy as it can use. Also, your program will be easier to
: read, more likely to be maintained (and maintained correctly), and
: far less likely to send a space probe to the wrong planet because
: nobody noticed the one equation in which you wrote 3.14195.
:
: When a constant is used in an expression, Perl replaces it with
: its value at compile time, and may then optimize the expression
: further. In particular, any code in an "if (CONSTANT)" block will
: be optimized away if the constant is false.
