Hello,
i have some variables say:
x=1.4
y=3.7
I wish to round off these values to :
x = 2 (after rounding off)
y = 4 (after rounding off)
I am stuck.
Please help. (7 Replies)
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 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)
I had a person bring an interesting problem to me that appears to involve some sort of rounding inside awk. I've verified this with awk and nawk on Solaris as well as with gawk 3.1.5 on a Linux box.
The original code fragment he brought me was thus:
for (index=0; index < 1; index=index+.1)

Hello Guys,
I'm very new on here and require some help matching up and printing some columns using awk.
I have two text files. The first file has Longitude data in column 1 (lon.txt) and the second one (node.txt) has again another Longitude data in column 1 (not exact as the first one) + in... (7 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,
Would be great if you help me with how to round up to whole number from my input values like
2.99996,2.17890,3.00002,-2.3456,-2.7890
o/p should be like 3,2,3,-2,-3
thnks in adv!!!!

Hello Guys,
I have a floating point number 1.14475E+15 I want to convert this number in to full number (Integer or Big integer). I tried couple of functions it did not work. When I use INT=${FLOAT/.*} I am getting value as 1. I don't want a truncated value

fenv - floating-point environment macros and functions
SYNOPSIS DESCRIPTION
The header declares two types and several macros and functions to provide access to the floating-point environment. The floating-point
environment refers collectively to the floating-point status flags and control modes. A floating-point status flag is a system variable
whose value is set (but never cleared) when a floating-point exception is raised, which occurs as a side effect of exceptional floating-
point arithmetic to provide auxiliary information. A floating-point control mode is a system variable whose value may be set by the user
to affect the subsequent behavior of floating-point arithmetic; on HP 9000 and HP Integrity servers the control modes include the rounding
direction mode, the gradual/flush-to-zero underflow mode, and the trap enables.
For HP-UX 11i v3 September 2008 Update (and later) for Integrity servers, the floating-point environment also includes the rounding direc-
tion mode for decimal floating point, which is independent of the rounding direction mode for binary floating point. Both binary and deci-
mal floating point use the same status flags.
The following types are defined:
Represents the entire floating-point environment.
Represents the floating-point exception flags collectively.
The following macros represent the floating-point status flags. They are defined as integral constant expressions with values such that
bitwise ORs of all combinations of the macros result in distinct values.
The inexact exception.
The division-by-zero exception.
The underflow exception.
The overflow exception.
The invalid operation exception.
The bitwise OR of all exception macros.
The following macros represent the rounding direction modes for binary floating point. They are defined as integral constant expressions
with distinct nonnegative values.
The round-to-nearest rounding direction mode.
The round-toward-positive-infinity rounding direction mode.
The round-toward-negative-infinity rounding direction mode.
The round-toward-zero rounding direction mode.
The following macro is defined as a pointer to const-qualified
The default floating-point environment.
To the ISO/IEC C99 specified facilities, the HP implementation adds four HP-specific functions: and

They are defined as integral constant expressions with distinct nonnegative values.
The round-to-nearest decimal rounding direction mode with ties

The round-toward-positive-infinity decimal rounding direction mode.
The round-toward-negative-infinity decimal rounding direction mode.
The round-toward-zero decimal rounding direction mode.
