There is one more glitch, am sorry for missing this out. I have some rows with entirely null values and as such using the previous code I ended up with getting fatal error (attempted division by zero). how can it be resolved? how to tell the script that when all values in the row is null (NaN), put NaN on that corresponding row average.
Many thanks.
Hello. Im just starting to learn awk so hang in there with me...I have a large text file formatted as such everything is in a single column

Hello everyone
I am doing a join command. Obviously, before I need two files sorted first. ( Both files have headers and have about 2 million lines each one )
The problem is, one of the files has null values in the key to sort (which is the first filed ). For example I have the original... (4 Replies)

cexpf
CEXP(3) BSD Library Functions Manual CEXP(3)NAME
cexp -- complex exponential function
SYNOPSIS
#include <complex.h>
double complex
cexp(double complex z);
long double complex
cexpl(long double complex z);
float complex
cexpf(float complex z);
DESCRIPTION
cexp(z) returns the complex exponential of z.
cexp(conj(z)) = conj(cexp(z)), for all complex floating-point numbers z.
SPECIAL VALUES
The conjugate symmetry of cexp() is used to abbreviate the specification of special values.
cexp(+-0 + 0i) returns 1 + 0i.
cexp(x + inf i) returns NaN + NaN i, and raises the invalid flag, for finite x.
cexp(x + NaN i) returns NaN + NaN i, for finite x.
cexp(inf + 0i) returns inf + 0i.
For the following two cases, cis(y) denotes cos(y) + I*sin(y).
cexp(-inf + yi) returns 0*cis(y), for finite y.
cexp(inf + yi) returns inf*cis(y), for finite nonzero y.
cexp(-inf + inf i) returns -0 + 0i.
cexp(inf + inf i) returns -inf + NaN i, and raises the invalid flag.
cexp(-inf + NaN i) returns -0 + 0i.
cexp(inf + NaN i) returns -inf + NaN i.
cexp(NaN + 0i) returns NaN + 0i.
cexp(NaN + yi) returns NaN + NaN i for all nonzero numbers y.
cexp(NaN + NaN i) returns NaN + NaN i.
SEE ALSO exp(3)clog(3)complex(3)STANDARDS
The cexp() function conforms to ISO/IEC 9899:2011.
