Depending on the fractional resolution you require you can scale up all the numbers and use the fixed-point arithmetics. Other than this - it's not possible to have FP in shell as FP instructions are not a must-have for a Unix system machine and shells should be as portable as possible. For same reason i.e. Linux kernel does not have any floating point operation as well.
frans:
Below script: is a valid shell script performing FP arithmetics. But I know what you meant.

So the first time I am getting o.1 which I wanted.But from the next... (4 Replies)

Hi,
I am compiling "HelloWorld" C progam on 32-bit CentOS and i want to execute it on 64-bit CentOS architecture.
For that i copied the a.out file from 32-bit to 64-bit machine, but while executing a.out file on 64bit machine I am getting "Floating point exception error".

Hi,
Could any one tell me how to compare to floating point no. using test command. As -eq option works on only intergers.
i=5.4
if
then
echo "equal"
else
echo "not equal"
fi
here output will be equal even though no. are unequal.
Thanks,

Hi,
I wish to compare the CPU LOAD 1 min with 5mins and 15mins.
If 1 min's CPU LOAd spike 3% compare to 5 mins or 15 mins CPU Load, it is warning.

platform::shell
platform::shell(n) Tcl Bundled Packages platform::shell(n)
__________________________________________________________________________________________________________________________________________________NAME
platform::shell - System identification support code and utilities
SYNOPSIS
package require platform::shell ?1.1.4?
platform::shell::generic shell
platform::shell::identify shell
platform::shell::platform shell
_________________________________________________________________DESCRIPTION
The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.
This package allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
requirement is that the other shell (identified by its path), is actually executable on the current machine.
While for most platform this means that the architecture of the interrogated shell is identical to the architecture of the running shell
this is not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.
For applications like a code repository it is important to identify the architecture of the shell which will actually run the installed
packages, versus the architecture of the shell running the repository software.
COMMANDS
platform::shell::identify shell
This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.
platform::shell::generic shell
This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.
platform::shell::platform shell
This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
KEYWORDS
operating system, cpu architecture, platform, architecture
