In other words, multiplying a number by 10 and then dividing the result by 10 results in the original number.
So, using an alternate formula...
Code:
$ cat calc2
#! /usr/bin/ksh
bc -l |&
print -p scale=6
while read dbm?"enter dBm --> "; do
print -p "e(($dbm-30)*l(10)/10)"
read -p watt
echo "dBm = $dbm watt = $watt"
done
echo
exit 0
$ ./calc2
enter dBm --> 29.216870
dBm = 29.216870 watt = .835001
enter dBm --> 30.008670
dBm = 30.008670 watt = 1.001997
enter dBm -->|

SVK::Log::ChangedPaths(3) User Contributed Perl Documentation SVK::Log::ChangedPaths(3) NAME
SVK::Log::ChangedPaths - partly lazy list of SVK::Log::ChangedPath objects SYNOPSIS
use SVK::Log::ChangedPaths; my $changed_paths = SVK::Log::ChangedPaths->new( $root ); for my $changed_path ( $changed_paths->paths() ) { ... } DESCRIPTION
An object of this class represents a collection of details about the files/directories that were changed in a particular revision. Some log filters want access to information about which paths were affected during a certain revision and others don't. Using this object allows the calculation of path details to be postponed until it's truly needed. METHODS
new Accepts the return value of "SVK::Path->root()" as a parameter and constructs a SVK::Log::ChangedPaths object from it. paths Returns a list of SVK::Log::ChangedPath objects each of which represents the details of the changes to a particular path. DIAGNOSTICS
None CONFIGURATION AND ENVIRONMENT
SVK::Log::ChangedPaths requires no configuration files or environment variables. DEPENDENCIES
