Using sed to delete everything after "space"

Hi,

I have a lot of string texts which normally should only contain a single float so that I can put this float into a variable.
This stings are generated by a grep command out of a large html file.
sometimes a value that I want to grep is found more than once, so that the resulting sting contains the value more than once, too.
Example:
"14.5 14.5"
So my idea was to use the sed command to delete everything after the first found " ". But I am not able to set the parameters for that sed command right.
I hope someone can help me with that...

Thanks,
Stefan

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
