```EXP(3)							   BSD Library Functions Manual 						    EXP(3)

NAME
exp, expf, exp2, exp2f, expm1, expm1f, -- exponential functions

LIBRARY
Math Library (libm, -lm)

SYNOPSIS
#include <math.h>

double
exp(double x);

float
expf(float x);

double
exp2(double x);

float
exp2f(float x);

double
expm1(double x);

float
expm1f(float x);

DESCRIPTION
The exp() and the expf() functions compute the base e exponential value of the given argument x.

The exp2(), and exp2f() functions compute the base 2 exponential of the given argument x.

The expm1() and the expm1f() functions computes the value exp(x)-1 accurately even for tiny argument x.

RETURN VALUES
These functions will return the appropriate computation unless an error occurs or an argument is out of range.  The functions exp() and
expm1() detect if the computed value will overflow, set the global variable errno to ERANGE and cause a reserved operand fault on a VAX.

math(3)

STANDARDS
The exp() functions conform to ANSI X3.159-1989 (``ANSI C89'').  The exp2(), exp2f(), expf(), expm1(), and expm1f() functions conform to
ISO/IEC 9899:1999 (``ISO C99'').

HISTORY
The exp() functions appeared in Version 6 AT&T UNIX.  The expm1() function appeared in 4.3BSD.

## reg exp question

Hi, Should be a difference between ']]*' and ']+' ? I use them in bash with sed and grep. Thanks

## Sorting exponential notation

Hi, I just want to sort my file with exponential notation. For example: 1;2;4;s 1;5e-01;4;s 1;1;4;s I used sort -gk2, but it does not sort in the correct way. What's wrong?

## list length

Hello, How can I change this code a=\$(egrep "exp" \$logFiles -oh); aCount=\$(egrep "exp" \$logFiles -oh| wc -l); to something like this a=\$(egrep "exp" \$logFiles -oh); aCount = \$a| wc -l What I mean I do not want to execute the egrep twice because it takes a lot of time Regards

## Exponential issues

I have the below awk command to search a row and find the line number. It returns the value in exponential. I understand we can use the print "%.0f\n" to convert the exponential. I wanted to have this in my awk command. Can anyone advise bnd=`awk '/^GS/{p=NR}\$0~"^ABC.*\\*"k{f=1}/^GE/&&f{print...
