Hi.

Changing the input data, this script works:
Code:
#!/usr/bin/env bash

# @(#) s1	Demonstrate proper scientific & engineering numerical syntax.

# Utility functions: print-as-echo, print-line-with-visual-space, debug.
pe() { for i;do printf "%s" "$i";done; printf "\n"; }
pl() { pe;pe "-----" ;pe "$*"; }
db() { ( printf " db, ";for i;do printf "%s" "$i";done; printf "\n" ) >&2 ; }
db() { : ; }
C=$HOME/bin/context && [ -f $C ] && . $C awk

FILE=${1-data1}

pl " Input file $FILE:"
cat $FILE

pl " Results:"
awk '($1 <0.05) {print $1}' $FILE

exit 0

producing:
Code:
% ./s1

Environment: LC_ALL = C, LANG = C
(Versions displayed with local utility "version")
OS, ker|rel, machine: Linux, 2.6.26-2-amd64, x86_64
Distribution        : Debian GNU/Linux 5.0.7 (lenny) 
GNU bash 3.2.39
GNU Awk 3.1.5

-----
 Input file data1:
0.04
0.01
0.11
0.55
3.1*e-6
4.1e-6

-----
 Results:
0.04
0.01
4.1e-6
