Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:


I have an array with elements having decimal points say for instance .0069874 , .0012365 , .98752115 ,.0002332.

and I wish to print data only to 4 decimal places

    You can use printf

    printf("%0.4f ", $_) for (.0069874, .0012365, .98752115, .0002332);

    sprintf is the function you need. The documentation has lots of examples.

[james28909]: i figured out a neet trick
[Lady_Aleena]: james28909, what neat trick?
[james28909]: now if i have packed a script into a PDK exe, and misplaced the source, i can print it.
[james28909]: but you have to prepare for it first by adding this to the source
[james28909]: seek DATA, 0, 0; while (<DATA>) { print; }
[Lady_Aleena]: Sounds interesting. Have you written a meditation or cool use for it?
[Lady_Aleena]: It might be something PerlMonks at large would be interested in.
