Hello. I just found out about awk, and it appears that this could handle the problem I'm having right now.
I first stumbled on the thread How to extract first and last line of different record from a file, and that problem is almost similar to mine.
In my case, an ASCII file will contain the... (0 Replies)
hi there
I'm very new in programing and i've started with awk.
I'm processing 200 data files and I need to do some precessing on them.
The files have 3 columns with N-lines
for each line a have on the first and second value is the same for all the files and only the third is variable. like... (2 Replies)

Hi everyone
I am very new at awk but think that that might be the best strategy for this. I have a matrix very similar to a correlation matrix and in practical terms I need to convert it into a list containing the values from the matrix (one value per line) with the first field of the line (row... (5 Replies)

pow(3M) Mathematical Library Functions pow(3M)NAME
pow, powf, powl - power function
SYNOPSIS
cc [ flag... ] file... -lm [ library... ]
#include <math.h>
double pow(double x, double y);
float powf(float x, float y);
long double powl(long double x, long double y);
DESCRIPTION
These functions compute the value of x raised to the power y, x**y. If x is negative, y must be an integer value.
RETURN VALUES
Upon successful completion, these functions return the value of x raised to the power y.
For finite values of x < 0, and finite non-integer values of y, a domain error occurs and either a NaN (if representable), or an implemen-
tation-defined value shall be returned.
If the correct value would cause overflow, a range error occurs and pow(), powf(), and powl() return HUGE_VAL, HUGE_VALF, and HUGE_VALL,
respectively.
If x or y is a NaN, a NaN is returned unless:
o For any finite value of y, if x is +1 and y is either +-Inf or NaN and the application is SUSv3-conforming (see standards(5)), 1.0 is
returned.
o For any value of x (including NaN), if y is +-0, 1.0 is returned.
For any odd integer value of y > 0, if x is +-0, +-0 is returned.
For y > 0 and not an odd integer, if x is +-0, +0 is returned.
If x is -1, and y is +-Inf, 1.0 is returned.
For |x| < 1, if y is -Inf, +Inf is returned.
For |x| > 1, if y is -Inf, +0 is returned.
For |x| < 1, if y is +Inf, +0 is returned.
For |x| > 1, if y is +Inf, +Inf is returned.
For y an odd integer < 0, if x is -Inf, -0 is returned.
For y < 0 and not an odd integer, if x is -Inf, +0 is returned.
For y an odd integer > 0, if x is -Inf, -Inf is returned.
For y > 0 and not an odd integer, if x is -Inf, +Inf is returned.
For y < 0, if x is +Inf, +0 is returned.
For y > 0, if x is +Inf, +Inf is returned.
For y an odd integer < 0, if x is +-0, a pole error occurs and +-HUGE_VAL, +-HUGE_VALF, and +-HUGE_VALL are returned for pow(), powf(), and
powl(), respectively.
For y < 0 and not an odd integer, if x is +-0, a pole error occurs and HUGE_VAL, HUGE_VALF, and HUGE_VALL are returned for pow(), powf(),
and powl(), respectively.
For exceptional cases, matherr(3M) tabulates the values to be returned by pow() as specified by SVID3 and XPG3.
ERRORS
These functions will fail if:
Domain Error The value of x is negative and y is a finite non-integer.
If the integer expression (math_errhandling & MATH_ERREXCEPT) is non-zero, the invalid floating-point exception is raised.
The pow() function sets errno to EDOM if the value of x is negative and y is non-integral.
Pole Error The value of x is 0 and y is negative.
If the integer expression (math_errhandling & MATH_ERREXCEPT) is non-zero, the divide-by-zero floating-point exception is
raised.
Range Error The result overflows.
If the integer expression (math_errhandling & MATH_ERREXCEPT) is non-zero, the overflow floating-point exception is raised.
The pow() function sets errno to EDOM if the value to be returned would cause overflow.
USAGE
An application wanting to check for exceptions should call feclearexcept(FE_ALL_EXCEPT) before calling these functions. On return, if
fetestexcept(FE_INVALID | FE_DIVBYZERO | FE_OVERFLOW | FE_UNDERFLOW) is non-zero, an exception has been raised. An application should
either examine the return value or check the floating point exception flags to detect exceptions.
An application can also set errno to 0 before calling pow(). On return, if errno is non-zero, an error has occurred. The powf() and powl()
functions do not set errno.

Prior to Solaris 2.6, there was a conflict between the pow function in this library and the pow function in the libmp library. This con-
flict was resolved by prepending mp_ to all functions in the libmp library. See mp(3MP) for details.
