I have a file with 1 column and its data is as follows;
"Happy Hour, Party on 18"" staged on 20th."
Can anyone please suggest me how do I remove the embedded quote in data stage while reading this column.
awk or sed might be able to do the trick . but i am not sure how to accomplish this.

got a problem.
i have to get A to + 20.70
but i keep getting A + 20 in my logic below.
anyone can guide me on where i go wrong?
i understand it is a double, but i do not noe how to parse it to the function so that it can read in as 20.70 instead of just 20..
i highlighted the problem part... (1 Reply)
Hi.
this is my code:
set common2 = "1 2 3 4"
echo $common2
you can see that between 1 and 2 there is double space
but the output is

exp2
EXP(3) BSD Library Functions Manual EXP(3)NAME
exp, expf, expl, exp2, exp2f, exp2l, expm1, expm1f, expm1l, pow, powf -- exponential and power functions
LIBRARY
Math Library (libm, -lm)
SYNOPSIS
#include <math.h>
double
exp(double x);
float
expf(float x);
long double
expl(long double x);
double
exp2(double x);
float
exp2f(float x);
long double
exp2l(long double x);
double
expm1(double x);
float
expm1f(float x);
long double
expm1l(long double x);
double
pow(double x, double y);
float
powf(float x, float y);
DESCRIPTION
The exp(), expf(), and expl() functions compute the base e exponential value of the given argument x.
The exp2(), exp2f(), and exp2l() functions compute the base 2 exponential of the given argument x.
The expm1(), expm1f(), and the expm1l() functions compute the value exp(x)-1 accurately even for tiny argument x.
The pow() and the powf() functions compute the value of x to the exponent y.
ERROR (due to Roundoff etc.)
The values of exp(0), expm1(0), exp2(integer), and pow(integer, integer) are exact provided that they are representable. Otherwise the error
in these functions is generally below one ulp.
RETURN VALUES
These functions will return the appropriate computation unless an error occurs or an argument is out of range. The functions pow(x, y) and
powf(x, y) raise an invalid exception and return an NaN if x < 0 and y is not an integer.
NOTES
The function pow(x, 0) returns x**0 = 1 for all x including x = 0, infinity, and NaN . Previous implementations of pow may have defined x**0
to be undefined in some or all of these cases. Here are reasons for returning x**0 = 1 always:
1. Any program that already tests whether x is zero (or infinite or NaN) before computing x**0 cannot care whether 0**0 = 1 or not. Any
program that depends upon 0**0 to be invalid is dubious anyway since that expression's meaning and, if invalid, its consequences vary
from one computer system to another.
2. Some Algebra texts (e.g. Sigler's) define x**0 = 1 for all x, including x = 0. This is compatible with the convention that accepts
a[0] as the value of polynomial
p(x) = a[0]*x**0 + a[1]*x**1 + a[2]*x**2 +...+ a[n]*x**n
at x = 0 rather than reject a[0]*0**0 as invalid.
3. Analysts will accept 0**0 = 1 despite that x**y can approach anything or nothing as x and y approach 0 independently. The reason for
setting 0**0 = 1 anyway is this:
If x(z) and y(z) are any functions analytic (expandable in power series) in z around z = 0, and if there x(0) = y(0) = 0, then
x(z)**y(z) -> 1 as z -> 0.
4. If 0**0 = 1, then infinity**0 = 1/0**0 = 1 too; and then NaN**0 = 1 too because x**0 = 1 for all finite and infinite x, i.e., inde-
pendently of x.
