bc is still an integer calculator, it just tracks the decimal point and adjusts later.
You can round up the same way in bc the same way you would in pure integer math. Add 0.5 (times 100) before you divide. Numbers that would round up will bump past nine, numbers that round down won't.
Hi All,
How we can handle decimals in (Float) in UNIX.

Hi,
I am trying to find if there is a way to convert regular decimal values to Paced decimal values. I tried to find a c program but I could get a Packed converted to regular decimal not the other way round.

Hello,
I want to run a loop with non-integer values (which I know I can't) so I've created a loop of integers and divided it by 10. However, these values are always rounded down to 1 significant figure. How do I get the script to keep and use the decimal value?
My script is as follows

round
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).)
