Hi All !
I am just trying to print bash variable in awk statement as string
here is my script
n=1
for file in `ls *.tk |sort -t"-" -k2n,2`; do

awk '{print "'$ak'",$0}' OFS="\t" $file
n=$((n+1))
unset ak
doneI am getting following error

Hello all! I've looked all over the internet and this site and have come up a loss with an easy way to make a bash script to do what I want to do. I have a file with a naming convention as follows:

Hi Friends,
I've an exponent value like,
$val="9.57669e-05";
I want to convert this value to floating point value in PERL scripting.
I tried googling for the solution, and also asked many perl friends. Unfortunately, I didn't get answer.
Could you please help me?
Thanks in advance... (4 Replies)
Here's a program and its pretty simple .It requires file handling and some calculations but on running it I am not getting the required result.It seems that the code outside the file read's outer while loop is not executing e.g the print statement is not being printed.Plz Help!

Hi,
see the simple code below
double i;
i=8080.9940;
printf(" val :%.30f\n",i);
output i m getting is
val :8080.993999999999700000000000000
when i m expecting
val :8080.9940
what happens?how can i avoid it?
thanks... (2 Replies)
float.h(3HEAD) Headers float.h(3HEAD)NAME
float.h, float - floating types
SYNOPSIS
#include <float.h>
DESCRIPTION
The characteristics of floating types are defined in terms of a model that describes a representation of floating-point numbers and values
that provide information about an implementation's floating-point arithmetic.
The following parameters are used to define the model for each floating-point type:
s sign (+-1)
b base or radix of exponent representation (an integer >1)
e exponent (an integer between a minimum emin and a maximum emax)
p precision (the number of base-b digits in the significand)
fk non-negative integers less than b (the significand digits)
In addition to normalized floating-point numbers (f1>0 if x!=0), floating types might be able to contain other kinds of floating-point num-
bers, such as subnormal floating-point numbers (x!=0, e=emin, f1=0) and unnormalized floating-point numbers (x!=0, e=emin, f1=0), and val-
ues that are not floating-point numbers, such as infinities and NaNs. A NaN is an encoding signifying Not-a-Number. A quiet NaN propagates
through almost every arithmetic operation without raising a floating-point exception; a signaling NaN generally raises a floating-point
exception when occurring as an arithmetic operand.
The accuracy of the library functions in math.h(3HEAD) and complex.h(3HEAD) that return floating-point results is defined on the libm(3LIB)
manual page.
All integer values in the <float.h> header, except FLT_ROUNDS, are constant expressions suitable for use in #if preprocessing directives;
all floating values are constant expressions. All except DECIMAL_DIG, FLT_EVAL_METHOD, FLT_RADIX, and FLT_ROUNDS have separate names for
all three floating-point types. The floating-point model representation is provided for all values except FLT_EVAL_METHOD and FLT_ROUNDS.
The rounding mode for floating-point addition is characterized by the value of FLT_ROUNDS:
-1 Indeterminable.
0 Toward zero.
1 To nearest.
2 Toward positive infinity.
3 Toward negative infinity.
The values of operations with floating operands and values subject to the usual arithmetic conversions and of floating constants are evalu-
ated to a format whose range and precision might be greater than required by the type. The use of evaluation formats is characterized by
the architecture-dependent value of FLT_EVAL_METHOD:
-1 Indeterminable.
0 Evaluate all operations and constants just to the range and precision of the type.
1 Evaluate operations and constants of type float and double to the range and precision of the double type; evaluate long double
operations and constants to the range and precision of the long double type.
2 Evaluate all operations and constants to the range and precision of the long double type.
The values given in the following list are defined as constants.
o Radix of exponent representation, b.
FLT_RADIX
o Number of base-FLT_RADIX digits in the floating-point significand, p.
FLT_MANT_DIG
DBL_MANT_DIG
LDBL_MANT_DIG
o Number of decimal digits, n, such that any floating-point number in the widest supported floating type with pmax radix b digits can be
rounded to a floating-point number with n decimal digits and back again without change to the value.
DECIMAL_DIG
o Number of decimal digits, q, such that any floating-point number with q decimal digits can be rounded into a floating-point number
with p radix b digits and back again without change to the q decimal digits.
FLT_DIG
DBL_DIG
LDBL_DIG
o Minimum negative integer such that FLT_RADIX raised to that power minus 1 is a normalized floating-point number, emin.
FLT_MIN_EXP
DBL_MIN_EXP
LDBL_MIN_EXP
o Minimum negative integer such that 10 raised to that power is in the range of normalized floating-point numbers.
FLT_MIN_10_EXP
DBL_MIN_10_EXP
LDBL_MIN_10_EXP
o Maximum integer such that FLT_RADIX raised to that power minus 1 is a representable finite floating-point number, emax.
FLT_MAX_EXP
DBL_MAX_EXP
LDBL_MAX_EXP
o Maximum integer such that 10 raised to that power is in the range of representable finite floating-point numbers.
FLT_MAX_10_EXP
DBL_MAX_10_EXP
LDBL_MAX_10_EXP
The values given in the following list are defined as constant expressions with values that are greater than or equal to those shown:
o Maximum representable finite floating-point number.
FLT_MAX
DBL_MAX
LDBL_MAX
The values given in the following list are defined as constant expressions with implementation-defined (positive) values that are less than
or equal to those shown:
o The difference between 1 and the least value greater than 1 that is representable in the given floating-point type, b**1 - p.
FLT_EPSILON
DBL_EPSILON
LDBL_EPSILON
o Minimum normalized positive floating-point number, b**emin**-.
