Please post the exact and precise (to the last decimal place) range of the parameter or parameters you are trying to validate. The Shell normally deals with integers ... but there is always another way. I think that my post is the only one which works so far. The awk and perl programmers have kept quiet so far ... perhaps because we are all having difficulty visualising your computer.
Do you have any computer programming languages available on your computer - expecially any in which you have expertise?
Hey Methyl,
That was so nice of you in taking time to write a detailed message.
It is an already being used shell script (program.sh) on my GNU Linux server.
The program was developed by another person that accepted only whole numbers(1,2, 3, 4, .....) but not decimals.
I just added the " | bc " to my program and it works now.
Earlier before, the first line in my code used to be #!/bin/sh and it gave me some errors saying cat and sed commands couldn't be found.
But, now I changed it to #!/bin/bash and the program is running without my earlier "arithmetic errors". I will let this post know how my output or errors are headed to.
Hello
You know how to ask for the existence of one parameter and depending about it then do something, example:
Original script:
###################
USER=$1
PASS=$2
program1 $USER $PASS
###################
Desired shell
###################
USER=$1
PASS=$2
ARCH=$3
if
then

round
ROUND(3) 1 ROUND(3)round - Rounds a floatSYNOPSIS
float round (float $val, [int $precision], [int $mode = PHP_ROUND_HALF_UP])
DESCRIPTION
Returns the rounded value of $val to specified $precision (number of digits after the decimal point). $precision can also be negative or
zero (default).
Note
PHP doesn't handle strings like "12,300.2" correctly by default. See converting from strings.
PARAMETERS
o $val
- The value to round
o $precision
- The optional number of decimal digits to round to.
o $mode
- Use one of the following constants to specify the mode in which rounding occurs.
+--------------------+---------------------------------------------------+
| Constant | |
| | |
| | Description |
| | |
+--------------------+---------------------------------------------------+
| | |
| PHP_ROUND_HALF_UP | |
| | |
| | Round $val up to $precision decimal places away |
| | from zero, when it is half way there. Making 1.5 |
| | into 2 and -1.5 into -2. |
| | |
| | |
|PHP_ROUND_HALF_DOWN | |
| | |
| | Round $val down to $precision decimal places |
| | towards zero, when it is half way there. Making |
| | 1.5 into 1 and -1.5 into -1. |
| | |
| | |
|PHP_ROUND_HALF_EVEN | |
| | |
| | Round $val to $precision decimal places towards |
| | the next even value. |
| | |
| | |
|PHP_ROUND_HALF_ODD | |
| | |
| | Round $val to $precision decimal places towards |
| | the next odd value. |
