ROUND(3) BSD Library Functions Manual ROUND(3)NAME
round, roundf, roundl -- round to nearest integral value
LIBRARY
Math Library (libm, -lm)
SYNOPSIS
#include <math.h>
double
round(double x);
float
roundf(float x);
long double
roundl(long double x);
DESCRIPTION
The round(), roundf(), and roundl() functions return the nearest integral value to x; if x lies halfway between two integral values, then
these functions return the integral value with the larger absolute value (i.e., they round away from zero).
SEE ALSO ceil(3), floor(3), ieee(3), lrint(3), lround(3), math(3), rint(3), trunc(3)STANDARDS
These functions conform to ISO/IEC 9899:1999 (``ISO C99'').
HISTORY
The round() and roundf() functions appeared in FreeBSD 5.3. The roundl() function appeared in FreeBSD 6.0.

ROUND(3) Linux Programmer's Manual ROUND(3)NAME
round, roundf, roundl - round to nearest integer, away from zero
SYNOPSIS
#include <math.h>
double round(double x);
float roundf(float x);
long double roundl(long double x);
DESCRIPTION
These functions round x to the nearest integer, but round halfway cases away from zero (regardless of the current rounding direction),
instead of to the nearest even integer like rint().
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
POSIX 1003.1-2001 contains 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 numbers the
maximum value of the exponent is 128 (resp. 1024), and the number of mantissa bits is 24 (resp. 53).)
CONFORMING TO
C99.

Hello,
In a unix shell script,i want to round a variabele to a nearest number
Ex: set count=104.4
How can i round that to 105.?
Thanks,

Hi Friends,
I need a help again in awk.
I just need to round up a value.
Eg Say x=5.664584525
I need to display x=5.66 means round. How can i do round in UNIX. (6 Replies)

i'm a newbie here, i need help with a shell script.
for a given number, if it is greater than ten round to the nearest 10
same for 100, if it is greater than 100 round to the nearest 100, and same for 1000.
i'm confused how to start this...
its supposed to look like this

Hey everyone, I was wondering if i am able to write a sed command to round a number to two decimal places. So for example:
1.58674
would be
1.58
I just want to chop off the numbers to the right of the second digit after the period. I know this is probably trivial but the closest i got was... (8 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
