Matching a decimal number?

Hi everyone!

Easy question for everyone. I'm trying to run a command line to find an exact match of a decimal number within a file. The number can be a positive OR negative number. For instance, if I want to find only the number -1 in the file that has:

Code:
-17.6
-17
-16.3
-16.2
-15.7
-15.3
-15.2
-1
-14.7
-14.3
-11
-10.9
-10.1
-10
-9.1
-8.1

how can I do this?
I tried cat myfile.asc | sed -n '/-1/ p' but this doesn't seem to work :-(

Thanks!!

Locale::Codes::LangFam(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangFam(3pm)

NAME
Locale::Codes::LangFam - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangFam; $lext = code2langfam('apa'); # $lext gets 'Apache languages' $code = langfam2code('Apache languages'); # $code gets 'apa' @codes = all_langfam_codes(); @names = all_langfam_names(); DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in ISO 639-5. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5 language family codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langfam('apa','alpha'); $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages. This is the default code set. ROUTINES
