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

Hi Guys,
I am generating a statistical report , below is the snippet of the code :
Now, $nSlices stands for the time duration,meaning,the statistics will be displayed for that particular time duration. Trouble is, for certain values of $totalTime (which is the end time - start time ), i... (9 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)
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 all of you,

I have a number, which I want to convert into the nearest floating number upto two places after the decimal point.
E.g.
1.2346 will become 1.23
but
1.2356 will become 1.24 .
Similarly
0.009 will be 0.01
and
0.001 will be 0.00 or 0.0 (not 0, wnat to keep the decimal... (1 Reply)

ceill
CEIL(3) Linux Programmer's Manual CEIL(3)NAME
ceil, ceilf, ceill - ceiling function: smallest integral value not less than argument
SYNOPSIS
#include <math.h>
double ceil(double x);
float ceilf(float x);
long double ceill(long double x);
DESCRIPTION
These functions round x up to the nearest integer.
RETURN VALUE
The rounded integer value. If x is integral or infinite, x itself is returned.
ERRORS
No errors other than EDOM and ERANGE can occur. If x is NaN, then NaN is returned and errno may be set to EDOM.
NOTES
SUSv2 and POSIX 1003.1-2001 contain text about overflow (which might set errno to ERANGE, or raise an exception). In practice, the result
cannot overflow on any current machine, so this error-handling stuff is just nonsense. (More precisely, overflow can happen only when the
maximum value of the exponent is smaller than the number of mantissa bits. For the IEEE-754 standard 32-bit and 64-bit floating point num-
bers the maximum value of the exponent is 128 (resp. 1024), and the number of mantissa bits is 24 (resp. 53).)
CONFORMING TO
The ceil() function conforms to SVID 3, POSIX, BSD 4.3, ISO 9899. The other functions are from C99.
