Hello,
I am using bash shell on Linux OS, May i please know why is it rounding for big numbers but not for others, is there a workaround to print it as it is with out round off?
Hello again.
I'm trying to use BC to calculate some numbers in a shell script.
I want to have the numbers rounded off to 1 decimal place.
for example:
initsize=1566720
zipsize=4733
I'm trying to get the ratio between them. the equation is:
(($initsize-$zipsize)/$initsize)*100
so... (3 Replies)
Hi,
Can any one help me in finding a solution for rounding off to 2 decimal places.
I am using the following code:
VAR1=.01292105263157894736
VAR2=`echo "scale=2; $VAR1 * 100" | bc -l`
The result I 'm getting is
1.29210526315789473600
But I need the output as 1.29
Thanks

Hello,
I searched a lot on this Forum.
Please help me with the below problem.
I want to divide two numbers and the result should be the next nearest whole number.
E.G. Dividing 10.8/5 ideally gives 2.16. But the result should be 3 i.e. rounded off to the next whole number.
Any help will... (2 Replies)

Hi,
I am currently using tcsh
I am trying to round a decimal number to the ten-thousandths place
For instance:
1.23456 is rounded up towards 1.2346
I am not looking for truncation, but for rounding. Anyone know how to do this with awk or expr?
Thanks (2 Replies)
Hi,
I have managed to round up numbers by using the following command:
echo "5.54" | awk '{printf "%.0f\n", $1}'
result
6
How can I round up all the numbers in a column in a file and print the lines with the new calculated totals?
Thanks, (3 Replies)
Dear Experts,
I'm trying to find a way to round a number but in this way:
14367.577 ---> 14000
I used the following to round the number to the closer integer:
echo $var|awk '{print int($1+0.5)}'
and also:
xargs printf "%1.0f"
However, they don't work for my above... (9 Replies)
Hi guys,
could someone throw some light on the following behaviour of printf (I'll start with info about the system and the tool/shell/interpreter versions)?:

fesetprec
fesetprec(3M) Mathematical Library Functions fesetprec(3M)NAME
fesetprec, fegetprec - control floating point rounding precision modes
SYNOPSIS
cc [ flag... ] file... -lm [ library... ]
#include <fenv.h>
int fesetprec(int prec);
int fegetprec(void);
DESCRIPTION
The IEEE 754 standard defines rounding precision modes for systems that always deliver intermediate results to destinations in extended
double precision format. These modes allow such systems to deliver correctly rounded single and double precision results (in the absence of
underflow and overflow) with only one rounding.
The fesetprec() function sets the current rounding precision to the precision specified by prec, which must be one of the following values
defined in <fenv.h>:
FE_FLTPREC round to single precision
FE_DBLPREC round to double precision
FE_LDBLPREC round to extended double precision
The default rounding precision when a program starts is FE_LDBLPREC.
The fegetprec() function returns the current rounding precision.
RETURN VALUES
The fesetprec() function returns a non-zero value if the requested rounding precision is established and 0 otherwise.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
|Architecture |Intel (see below) |
|Availability |SUNWlibms |
|Interface Stability |Stable |
|MT-Level |MT-Safe |
+-----------------------------+-----------------------------+
These functions are not available on SPARC systems because SPARC processors deliver intermediate results to destinations in single or dou-
ble format as determined by each floating point instruction.
