Greetings,
I am slowly learning a few things but am far from being an expert. I am at the point now that I
would like to be able write some ANSI C code on HP-UX 10.2. Just a hobbie... I am just using cc,
which came with the HP-UX 10.2 ...
I don't have the manuals for the development environment...
Anyway, I have the following sample code that illustrates that I am missing a library file
when cc attempts to link??? That is the conclusion I have come to.
I have looked through man pow, and man math and have not found the information I am looking for.
I am not sure 1) which library file is missing and 2) the syntax I need to use to poperly compile
and link in the object files.
Following is sample code that illustrates the issue I am having with cc
Thanks in advance,
Dirk

Hi,
I am getting the following error while compiling my C++ program using GCC compiler.

Hi my file is suffering from some weird text symbols like a question mark inside of a square. I don't know how to remove these. I tried to remove UTF accents with command
sed -e 's/^*Width:*//' -e 's/*$//'`
but no use
. Could u guyz plz help me. (4 Replies)
I noticed that sometimes there is "~#" or "~$" in the terminal. What is that? I can't make any research in google because I don't know what are they called. I even tried reading pdf's or books but unfortunately, I wasn't lucky to find out. Maybe I was not persistent enough but I am really... (3 Replies)
Hi, I need to look at a recent copy of /usr/include/errno.h from AIX 7.2 to check some symbols. In particular, I'm curious if it defines EOWNERDEAD and ENOTRECOVERABLE. Can someone who has access to 7.2 please check for me? Thanks! (1 Reply)

exp2l
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.
