ECVT(3) Library Functions Manual ECVT(3)NAME
ecvt, fcvt, gcvt - output conversion
SYNOPSIS
char *ecvt(value, ndigit, decpt, sign)
double value;
int ndigit, *decpt, *sign;
char *fcvt(value, ndigit, decpt, sign)
double value;
int ndigit, *decpt, *sign;
char *gcvt(value, ndigit, buf)
double value;
char *buf;
DESCRIPTION
Ecvt converts the value to a null-terminated string of ndigit ASCII digits and returns a pointer thereto. The position of the decimal
point relative to the beginning of the string is stored indirectly through decpt (negative means to the left of the returned digits). If
the sign of the result is negative, the word pointed to by sign is non-zero, otherwise it is zero. The low-order digit is rounded.
Fcvt is identical to ecvt, except that the correct digit has been rounded for Fortran F-format output of the number of digits specified by
ndigits.
Gcvt converts the value to a null-terminated ASCII string in buf and returns a pointer to buf. It attempts to produce ndigit significant
digits in Fortran F format if possible, otherwise E format, ready for printing. Trailing zeros may be suppressed.
SEE ALSO printf(3)BUGS
The return values point to static data whose content is overwritten by each call.

Description
The routine converts the value to a null-terminated string of ndigit ASCII digits and returns a pointer thereto. The position of the radix
character relative to the beginning of the string is stored indirectly through decpt (negative means to the left of the returned digits).
If the sign of the result is negative, the word pointed to by sign is non-zero, otherwise it is zero. The low-order digit is rounded.
The routine is identical to except that the correct digit has been rounded for FORTRAN F-format output of the number of digits specified by
ndigits.
The routine converts the value to a null-terminated ASCII string in buf and returns a pointer to buf. It attempts to produce ndigit sig-
nificant digits in FORTRAN F format if possible, otherwise E format is used, ready for printing. Trailing zeros may be suppressed.
The symbol used to represent a radix character is obtained from the last successful call to category The symbol can be determined by call-
ing:
nl_langinfo (RADIXCHAR);
If category has not been called successfully, or if the radix character is not defined for a supported language, the radix character
defaults to a period (.).
International Environment
LC_NUMERIC If this environment is set and valid, uses the international language database named in the definition to determine radix
character rules.
LANG If this environment is set and valid, uses the international language database named in the definition to determine radix
character rules. If is defined, its definition supercedes the definition of
Restrictions
The return values point to static data whose content is overwritten by each call.

I have got a file that contains both single and double digits like this
10 3 48 39 20 6 8
and i want to add zeros in front of every single digit to become double digits like this

I have a file with a lot of lines (a lot!) that contain 10 digits between double quotes. ie "1726937489". The digits are random throughout, but always contain ten digits.
I can not for the life of me, (via scouring the internet and grep how-to manuals) figure out how to find this when I search.... (3 Replies)
Hi All,
I am having a file which contains negative numbers, wht i am doing is re-formattting the file(moving few columns and add few hard codings between), while reformatting i would want the negative numbers to have the sign as trailing rather than leading.

I would like to search between two a string. I thought this would be easy. The is always at the beginning of a line.
The code:
gawk '/^/{d=$1},/searchstring/,/^(d+1)/'
or
gawk '/^/,/searchstring/,/^/'
did not return the desired result.

Hi experts,
I have two values in the file :
For example :
partcamt = 72.90
partdamt=27.9
I need to convert these values into 6 digits and ignore the "." sign so that the desired desired output is :
total value= 0072000027900
Currently I am using the following code :
