- # This is a shell archive, meaning:
- # 1. Remove everything above the #! /bin/sh line.
- # 2. Save the resulting text in a file.
- # 3. Execute the file with /bin/sh (not csh) to create the files:
- # README
- # eurmpg
- # fpdivide.1
- # fpdivide.c
- # mpg.1
- # mpgdata
- # ukmpg

- cat << \SHAR_EOF > 'README'
- The enclosed files are an example of a floating point application
- written in Bourne shell scipt, with the aid of a short program,
- FPDIVIDE.
-
- FPDIVIDE will divide, multiply, add, and subtract floating point
- numbers, depending on its name.
-
- The sample application enclosed is a Fuel Economy Calculator,
- in versions for the US, UK, and the rest of the (decimal) world.
-
- While fuel economy is not such a hot topic in the US, I don't know
- of any other topic more frequently discussed when drivers of automobiles
- talk about their cars in Europe.
-
- This program will let you enter the distance driven and fuel consumed
- every time you fill your tank, and will then tell you how many miles
- to the gallon you have driven, or how many liters of fuel your have
- consumed per 100 km driven.
-
- It will optionally print out a short statement on the standard line printer.
-
- With minimal modifications, this program should also run under the
- MKS Toolkit implementation of the Korn Shell.
-
- FILES:
-
- README this file
- fpdivide.c the source for the floating point commands
- fpdivide.1 man page for the floating point commands
- mpg.1 man page for the MPG programs
- eurmpg European/Decimal version of MPG
- ukmpg UK/Imperial Gallons version of MPG
- usmpg US version of MPG
- mpgdata initial $HOME/.mpgdata file, all zeros
-
- I hope sombody finds this useful. I welcome your comments!

- .TH FPDIVIDE 1L Local
- .SH NAME
- fpdivide, fpmultiply, fpadd, fpsubtract \-
- floating point math programs for shell scripts
- .SH SYNOPSIS
- fpdivide
- .I num1 num2
- # performs the division
- .I num1 / num2
-
- fpmultiply
- .I num1 num2
- # performs the multiplication
- .I num1 * num2
-
- fpadd
- .I num1 num2

-
- .SH DESCRIPTION
- These commands, which are really links to the same program, perform
- the floating point arithmetical operations as listed above, and print
- their result (with a precision of two decimal digits) on the standard
- output.
-
- They are designed to add simple floating point arithmetic to Bourne and
- Korn shell scripts.
-
- .SH INSTALLATION
- Compile the source file,
- .I fpdivide.c,
- copy the resulting executable into your local
- .I bin
- directory, and make additional links
- .I fpmultiply, fpadd,
- and
- .I fpsubtract
- to the same binary.

- .TH MPG 1L Local
- .SH NAME
- mpg, usmpg, ukmpg, eurmpg \- Miles Per Gallon, A Fuel Economy Calculator
- .SH SYNOPSIS
- mpg
- .SH DESCRIPTION
- .B Mpg
- is a
- .I fuel economy calculator,
- i.e. it calculates fuel consumption statistics for a motor vehicle.
-
- The program displays its results on the terminal screen, and optionally
- will produce a short statement on the standard line printer.
-
- There are three versions of the program, based on the fact that there are
- three (or rather, two and one half) systems of measurement commonly used
- to measure distance travelled and fuel consumed.
-
- .B USMPG
- is the American version of the program, requesting input in miles and
- US gallons.
-
- .B UKMPG
- is the British version of the program, requesting input in miles and Imperial
- gallons. Obviously, it is useful anywhere where this combination of
- measurements is used.
-
- .B EURMPG
- is the European or Decimal version of the program, requesting input in
- kilometers and liters. It is useful wherever the metric system has been fully
- implemented.
-
- All three versions of the program print their results both for the current
- tank filling, and for the average from the first time a particular user
- used the program (old data for this purpose is kept in a file in the user's
- home directory.
-
- All three versions print their results in three different formats:
- .nf
-
- - Miles per US Gallon
- - Miles per Imperial Gallon
- - Liters per 100 Kilometers
-
- .fi
- which to my knowledge covers all common conventions to measure fuel efficiency.
-
- The datafile $HOME/.mpgdata contains the total figures since the first time
- a particular user used the program, in the form of a single line of text.
- This line consists of five colon-delimited fields which contain the total miles,
- kilometers, US gallons, UK gallons, and liters. Here is a sample of the
- $HOME/.mpgdata file:
-
- .nf
- 598.35:957.36:21.50:18.15:81.71
- | | | | |
- miles | US Gall. | Liters
- kilometers UK Gall.
- .fi
- .SH INSTALLATION
- Make sure the floating point arithmetic commands (fpdivide.1) are available.
- Copy the shell scripts for the three versions to your local bin directory,
- and make an additional link
- .I mpg
- to the version you will most frequently use.
- Copy the file
- .I mpgdata
- to $HOME/.mpgdata for every user who will use the program.
- The file is compatible with all versions of the program, so the versions can
- be used alternatively with no modification to #HOME/.mpgdata necessary.
- .SH FILES
- $HOME/.mpgdata the datafile
