I would like to start coding on my mac, but I'm getting an error when I attempt to execute my script
-bash : testscript: command not found
I have verified that the #! line points to the correct directory.
If you have some insight it would be greatly appreciated!

Hi All,
I am new to pro*C. I have a select statement as
select a.ename,a.sal,a.empno from emp where &n=(select count(distinct(b.sal)) from emp b where a.sal<=b.sal
for this query I have to write a pro*C program. So can you please send me the complete code. Then I will foloow the same... (1 Reply)
HI,
Can some one guide me how to make changes to the script below so that it can load the history of a program to IT server ?
Format of data:
YYYYMMDD065959.dsk.log
YYYYMMDD235959.dsk.log
currently both are loaded together. Need to separate them as above format.
Thanks in advance.

rint
FLOOR(3M)FLOOR(3M)NAME
fabs, floor, ceil, rint - absolute value, floor, ceiling, and round-to-nearest functions
SYNOPSIS
#include <math.h>
double floor(x)
double x;
double ceil(x)
double x;
double fabs(x)
double x;
double rint(x)
double x;
DESCRIPTION
Fabs returns the absolute value |x|.
Floor returns the largest integer no greater than x.
Ceil returns the smallest integer no less than x.
Rint returns the integer (represented as a double precision number) nearest x in the direction of the prevailing rounding mode.
NOTES
On a VAX, rint(x) is equivalent to adding half to the magnitude and then rounding towards zero.
In the default rounding mode, to nearest, on a machine that conforms to IEEE 754, rint(x) is the integer nearest x with the additional
stipulation that if |rint(x)-x|=1/2 then rint(x) is even. Other rounding modes can make rint act like floor, or like ceil, or round
towards zero.
Another way to obtain an integer near x is to declare (in C)
double x; int k; k = x;
Most C compilers round x towards 0 to get the integer k, but some do otherwise. If in doubt, use floor, ceil, or rint first, whichever you
intend. Also note that, if x is larger than k can accommodate, the value of k and the presence or absence of an integer overflow are hard
to predict.
