If x is a shell variable whose value is a zero-padded integral string of some unspecified width, the following will increment the value, preserving padding/width so long as the value does not exceed the range representable with the initial quantity of digits:
That should work with ksh88, ksh93, pdksh, and bash (and probably others).
How to insert leading zeros into a left-justisfied zip code?
e.g. Zip code is written as 60320 which is left-justified to make it be read as 0060320.
We have to move it to right-justifiable then insert 2 leading zeros into it... ;) (1 Reply)
Hi All,
I am working with a fixed width file Forrmat.
C1 Number (10,3)
C2 Number (10,3)
e.g.
c1= 0000000100.000
c2= 0000000020.000
0000000100.0000000000020.000
I have to perform c1 - c2 . i.e. I want answer to be 0000000080.000. but I am loosing the leading zeros( only getting... (3 Replies)
Hi
I have a file in which I have 5 columns which are delimited by “|” as shown
ABC|12|YAK|METRIC|000000019.5
XYZ|10|ABX|META|000000002.5
Now my requirement is to take the last column trim the leading zero's for that column values and write back to the same file in the same... (7 Replies)
Hi all,
I have file with numeric values. I need to pad each value with leading zeros such that total lenght of each value is 16.
Example:
cat tmp.txt
502455
50255
5026
5027
5028
Output
0000000000502455

I have a list of numbers extracted and need to delete the leading zeros from them, but when i do so, the command I am using also deletes numbers that end in Zero as well. eg 10, 20, 30, etc
this is part of a larger script and the only way I can think of is to try and detect the 10,20 30 etc in... (19 Replies)

gcvt
ECVT(3) BSD Library Functions Manual ECVT(3)NAME
ecvt, fcvt, gcvt -- convert double to ASCII string
SYNOPSIS
#include <stdlib.h>
char *
ecvt(double value, int ndigit, int * restrict decpt, int * restrict sign);
char *
fcvt(double value, int ndigit, int * restrict decpt, int * restrict sign);
char *
gcvt(double value, int ndigit, char *buf);
DESCRIPTION
These functions are provided for compatibility with legacy code. New code should use the snprintf(3) function for improved safety and porta-
bility.
The ecvt(), fcvt() and gcvt() functions convert the double precision floating-point number value to a NUL-terminated ASCII string.
The ecvt() function converts value to a NUL-terminated string of exactly ndigit digits and returns a pointer to that string. The result is
padded with zeroes from left to right as needed. There are no leading zeroes unless value itself is 0. The least significant digit is
rounded in an implementation-dependent manner. The position of the decimal point relative to the beginning of the string is stored in decpt.
A negative value indicates that the decimal point is located to the left of the returned digits (this occurs when there is no whole number
component to value). If value is zero, it is unspecified whether the integer pointed to by decpt will be 0 or 1. The decimal point itself
is not included in the returned string. If the sign of the result is negative, the integer pointed to by sign is non-zero; otherwise, it is
0.
If the converted value is out of range or is not representable, the contents of the returned string are unspecified.
The fcvt() function is identical to ecvt() with the exception that ndigit specifies the number of digits after the decimal point (zero-padded
as needed).
The gcvt() function converts value to a NUL-terminated string similar to the %g printf(3) format specifier and stores the result in buf. It
produces ndigit significant digits similar to the %f printf(3) format specifier where possible. If ndigit does allow sufficient precision,
the result is stored in exponential notation similar to the %e printf(3) format specifier. If value is less than zero, buf will be prefixed
with a minus sign. A decimal point is included in the returned string if value is not a whole number. Unlike the ecvt() and fcvt() func-
tions, buf is not zero-padded.
RETURN VALUES
The ecvt(), fcvt() and gcvt() functions return a NUL-terminated string representation of value.
WARNINGS
The ecvt() and fcvt() functions return a pointer to internal storage space that will be overwritten by subsequent calls to either function.
The maximum possible precision of the return value is limited by the precision of a double and may not be the same on all architectures.
The snprintf(3) function is preferred over these functions for new code.
SEE ALSO printf(3), strtod(3)STANDARDS
The ecvt(), fcvt() and gcvt() functions conform to IEEE Std 1003.1-2001 (``POSIX.1'').
