[BASH] Regex for floating point number
Hey again,
I have a basic regex that tests if a number is a float.
Thank you.

Hi, guys,
today, I have copied a simple script which runs correctly on a computer to another one. But, the latter informs me:
Floating point exception!

I' using bash and I would like to use "bc" to compute the ratio of of two numbers and assign the ratio to a variable.

Any idea how to do it?
N.B. I cannot change the file to have 196.304492 / 615.348986 as the file is produced by... (14 Replies)

I have a script (vhs - video handler script, using ffmpeg) to encode videos.

At first it looked quite fine, but when changing from the first VOB... (9 Replies)

I have often found bash to be difficult when it comes to floating point numbers. I have data with rows of tab delimited floating point numbers.

test::useallmodules
Test::UseAllModules(3pm) User Contributed Perl Documentation Test::UseAllModules(3pm)
NAME
Test::UseAllModules - do use_ok() for all the MANIFESTed modules
SYNOPSIS
# basic usage
use strict;
use Test::UseAllModules;
BEGIN { all_uses_ok(); }
# if you also want to test modules under t/lib
use strict;
use Test::UseAllModules under => qw(lib t/lib);
BEGIN { all_uses_ok(); }
# if you have modules that'll fail use_ok() for themselves
use strict;
use Test::UseAllModules;
BEGIN {
all_uses_ok except => qw(
Some::Dependent::Module
Another::Dependent::Module
^Yet::Another::Dependent::.* # you can use regex
)
}
DESCRIPTION
I'm sick of writing 00_load.t (or something like that) that'll do use_ok() for every module I write. I'm sicker of updating 00_load.t when
I add another file to the distro. This module reads MANIFEST to find modules to be tested and does use_ok() for each of them. Now all you
have to do is update MANIFEST. You don't have to modify the test any more (hopefully).
EXPORTED FUNCTION
all_uses_ok
Does Test::More's use_ok() for every module found in MANIFEST. If you have modules you don't want to test, give those modules or some regex
rules as the argument. The word 'except' is ignored as shown above.
As of 0.11, you can also test modules under arbitrary directories by providing a directory list at the loading time (the word 'under' is
ignored as shown above). Modules under the lib directory are always tested.
PROTECTED FUNCTION
_get_module_list
Returns module paths to test. This function will not be exported. If you want to use this (see below), you always need to call it by the
full qualified name.
NOTES
As of 0.03, this module calls BAIL_OUT of Test::More if any of the use_ok tests should fail. (Thus the following tests will be ignored.
Missing or unloadable modules cause a lot of errors of the same kind.)
As of 0.12, you can add extra tests before/after all_uses_ok() if you explicitly declare test plan like this.
use strict;
use warnings;
use Test::More;
use Test::UseAllModules;
use Test::NoWarnings;
plan tests => Test::UseAllModules::_get_module_list() + 1;
all_uses_ok();
# and extra nowarnings test
SEE ALSO
There're several modules like this on the CPAN now. Test::Compile and a bit confusing Test::LoadAllModules try to find modules to test by
traversing directories. I'm not a big fun of them as they tend to find temporary or unrelated modules as well, but they may be handier
especially if you're too lazy to update MANIFEST every time.
