I know its a dumb question but can any one please explain me the difference of executing a shell script in the following 2 ways.
. script.sh
sh script.sh
I have a problem if I execute the following code as sh script.sh

Hi,
As all of us know that size of int is machine as well as compiler dependent
we can get the range and size of an int , float and char etc in
/usr/include/limits.h
header file of a compiler
but could any one tell me how to get info of precision of float and ... (6 Replies)
HI!
What is the notation which correspond to C's
doubleandfloatin Perl??
Please tell me.
Thanks.
Well what I want to do is, for example, calculatingsqrt(2)in two way: float and double. (5 Replies)
i am adding two floating point numbers and i want to store in a character pointer...
float f1 ;
float f2 ;
char *c = NULL;
printf("Enter 2 floating numbers\n");
scanf("%f %f",&f1,&f2);
f1 = f1+f2;
sprintf(c, "%f", f1 );

I have a file with 2 columns . One of the line looks like the following.
Is it possible to convert every float no in column 2 to integer.

What is use of this float IP?
How it is configured? (1 Reply)
Hi,
I have small problem to print float value in the fallowing code
float Cx, W,f=250000, Cr=92.00,pi=3.14;
W=2*pi*f;
Cx = 1/W.Cr; //Cx value will be come around like 7.07E-9.
printf("capacitance value: %.10f",Cx);
I am trying to print Cx value using above code but it was not... (3 Replies)

ceil
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);
Link with -lm.
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
ceilf(), ceill():
_ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L
|| /* Since glibc 2.19: */ _DEFAULT_SOURCE
|| /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE
DESCRIPTION
These functions return the smallest integral value that is not less than x.
For example, ceil(0.5) is 1.0, and ceil(-0.5) is 0.0.
RETURN VALUE
These functions return the ceiling of x.
If x is integral, +0, -0, NaN, or infinite, x itself is returned.
ERRORS
No errors occur. POSIX.1-2001 documents a range error for overflows, but see NOTES.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

CONFORMING TO
C99, POSIX.1-2001, POSIX.1-2008.
The variant returning double also conforms to SVr4, 4.3BSD, C89.
NOTES
SUSv2 and POSIX.1-2001 contain text about overflow (which might set errno to ERANGE, or raise an FE_OVERFLOW 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 (respectively, 1024), and the number of mantissa bits is 24 (respectively, 53).)
The integral value returned by these functions may be too large to store in an integer type (int, long, etc.). To avoid an overflow, which
will produce undefined results, an application should perform a range check on the returned value before assigning it to an integer type.
