Hell friends,
I wrote a script gets the summation of particular column using awk.
The awk output is given in scientific notation. How do I convert the scientific notation to normal.
My awk syntax : awk '{sum += $2} END { printf sum }' temprep.txt
Out put is like 1.5365e+07
I want it as... (2 Replies)
Hi,
I'm need to do some addition and multiplication of scientific nottaion numbers, in the form 34.23423e-10 for example.
I was echoing the list of numbers to stdout, then using bc -l, then I find that this does not seem to work for numbers with exponential notation. Could someone help me out... (1 Reply)
Hello there,
I have a script that must be written in bash that has to deal with reading in values from a file (in scientific notation), and requires executing some mathematical operations with them. What is the easiest way to go about doing this/converting it to float to use | bc, etc.?

Hello All,
Hope all is well,
Suppose I have a program that extracted data into a file called: progcros.in.
I attached the file but I renamed it progcros.txt. I think that my mess up the column alignment.
Anyways,
in several columns there are numbers listed, however the numbers... (4 Replies)

Hi,
I am trying to read a set of numbers that are in scientific notation into a file so I can do some math on them, but when I display the array contents the numbers aren't the same as the numbers in the file.
Could someone explain why? Thanks.

Hi everyone,
I need to convert some numbers that are written in scientific notation to normal notation.
Here is a sample line from my data file;

fcvt
ecvt(3C) Standard C Library Functions ecvt(3C)NAME
ecvt, fcvt, gcvt - convert floating-point number to 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
The ecvt(), fcvt() and gcvt() functions convert floating-point numbers to null-terminated strings.
ecvt()
The ecvt() function converts value to a null-terminated string of ndigit digits (where ndigit is reduced to an unspecified limit determined
by the precision of a double) and returns a pointer to the string. The high-order digit is non-zero, unless the value is 0. The low-order
digit is rounded. The position of the radix character relative to the beginning of the string is stored in the integer pointed to by decpt
(negative means to the left of the returned digits). The radix character 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.
fcvt()
The fcvt() function is identical to ecvt() except that ndigit specifies the number of digits desired after the radix point. The total num-
ber of digits in the result string is restricted to an unspecified limit as determined by the precision of a double.
gcvt()
The gcvt() function converts value to a null-terminated string (similar to that of the %g format of printf(3C)) in the array pointed to by
buf and returns buf. It produces ndigit significant digits (limited to an unspecified value determined by the precision of a double) in %f
if possible, or %e (scientific notation) otherwise. A minus sign is included in the returned string if value is less than 0. A radix
character is included in the returned string if value is not a whole number. Trailing zeros are suppressed where value is not a whole num-
ber. The radix character is determined by the current locale. If setlocale(3C) has not been called successfully, the default locale,
POSIX, is used. The default locale specifies a period (.) as the radix character. The LC_NUMERIC category determines the value of the
radix character within the current locale.
RETURN VALUES
The ecvt() and fcvt() functions return a pointer to a null-terminated string of digits.
The gcvt() function returns buf.
ERRORS
No errors are defined.
USAGE
The return values from ecvt() and fcvt() might point to thread-specific data that can be overwritten by subsequent calls to these functions
by the same thread.
For portability to implementations conforming to earlier versions of Solaris, sprintf(3C) is preferred over this function.
