is it not possible to simply di aritmetic without using bc or awk
i have tried folllowing operatrions but they support only integer types plz suggest me code for floating using values stored in the variables.the ans i get is integer and if i input floating values i get error numeric constant missing plz help

Hi all!
I am working with a problem to find the smallest floating point number that can be represented.
I am going in a loop ,stating with an initial value of 1.0 and then diving it by 10 each time thru the loop.
So the first time I am getting o.1 which I wanted.But from the next... (4 Replies)

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,

I am writing a script in zsh shell, it fetchs a number from a file using the awk command, store it as a variable, which in my case is a small number 0.62000. I want to change this number by multiplying it by 1000 to become 620.0 using the command in the script

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.
If 1 min's CPU LOAd spike 5% compare to 5 mins or 15 mins CPU Load, it is critical.
However I received following code error, I google it and... (10 Replies)
Hi guys...
I am working on limited basic set of maths routines for ksh93 that can be sourced as . ./ksh_math.sh and I am gobsmacked by its capabilities.
Although some big guns may already know this, I didn't, and ksh93 is easily able to do floating point numbers to floating point powers and... (16 Replies)

tcl_exprlong
Tcl_ExprLong(3) Tcl Library Procedures Tcl_ExprLong(3)__________________________________________________________________________________________________________________________________________________NAME
Tcl_ExprLong, Tcl_ExprDouble, Tcl_ExprBoolean, Tcl_ExprString - evaluate an expression
SYNOPSIS
#include <tcl.h>
int
Tcl_ExprLong(interp, expr, longPtr)
int
Tcl_ExprDouble(interp, expr, doublePtr)
int
Tcl_ExprBoolean(interp, expr, booleanPtr)
int
Tcl_ExprString(interp, expr)
ARGUMENTS
Tcl_Interp *interp (in) Interpreter in whose context to evaluate expr.
const char *expr (in) Expression to be evaluated.
long *longPtr (out) Pointer to location in which to store the integer value of the expression.
int *doublePtr (out) Pointer to location in which to store the floating-point value of the expression.
int *booleanPtr (out) Pointer to location in which to store the 0/1 boolean value of the expression.
_________________________________________________________________DESCRIPTION
These four procedures all evaluate the expression given by the expr argument and return the result in one of four different forms. The
expression can have any of the forms accepted by the expr command. Note that these procedures have been largely replaced by the object-
based procedures Tcl_ExprLongObj, Tcl_ExprDoubleObj, Tcl_ExprBooleanObj, and Tcl_ExprObj. Those object-based procedures evaluate an
expression held in a Tcl object instead of a string. The object argument can retain an internal representation that is more efficient to
execute.
The interp argument refers to an interpreter used to evaluate the expression (e.g. for variables and nested Tcl commands) and to return
error information.
For all of these procedures the return value is a standard Tcl result: TCL_OK means the expression was successfully evaluated, and
TCL_ERROR means that an error occurred while evaluating the expression. If TCL_ERROR is returned then the interpreter's result will hold a
message describing the error. If an error occurs while executing a Tcl command embedded in the expression then that error will be
returned.
If the expression is successfully evaluated, then its value is returned in one of four forms, depending on which procedure is invoked.
Tcl_ExprLong stores an integer value at *longPtr. If the expression's actual value is a floating-point number, then it is truncated to an
integer. If the expression's actual value is a non-numeric string then an error is returned.
Tcl_ExprDouble stores a floating-point value at *doublePtr. If the expression's actual value is an integer, it is converted to floating-
point. If the expression's actual value is a non-numeric string then an error is returned.
Tcl_ExprBoolean stores a 0/1 integer value at *booleanPtr. If the expression's actual value is an integer or floating-point number, then
they store 0 at *booleanPtr if the value was zero and 1 otherwise. If the expression's actual value is a non-numeric string then it must
be one of the values accepted by Tcl_GetBoolean such as "yes" or "no", or else an error occurs.
Tcl_ExprString returns the value of the expression as a string stored in the interpreter's result.
