ctanh -- complex hyperbolic tangent function
SYNOPSIS
double complex
ctanh(double complex z);
long double complex
ctanhl(long double complex z);
float complex
ctanhf(float complex z);
DESCRIPTION
ctanh(z) computes the hyperbolic tangent of the complex floating-point number z.
For all complex floating point numbers z,
ctanh(conj(z)) = conj(ctanh(z)),
ctanh(-z) = -ctanh(z).
SPECIAL VALUES
The symmetries of ctanh() are used to abbreviate the specification of special values.
ctanh(0 + 0i) returns 0 + 0i.
ctanh(0 + inf i) returns NaN + NaN i, and raises the invalid flag.
ctanh(0 + NaN i) returns NaN + NaN i.
ctanh(x + inf i) returns NaN + NaN i, and raises the invalid flag, for finite nonzero x.
ctanh(x + NaN i) returns NaN + NaN i, for finite nonzero x.
ctanh(inf + 0i) returns 1 + 0i.
ctanh(inf + yi) returns 1 +- 0i, for finite positive y, with the sign chosen to match the sign of sin(2y).
ctanh(inf + inf i) returns 1 + 0i.
ctanh(inf + NaN i) returns 1 + 0i.
ctanh(NaN + 0i) returns NaN + 0i.
ctanh(NaN + yi) returns NaN + NaN i, for nonzero numbers y.
ctanh(NaN + NaN i) returns NaN + NaN i.
NOTES SEE ALSO ctan(3)complex(3)STANDARDS
The ctanh() function conforms to ISO/IEC 9899:2011.

Hi,
I have a file that looks like this (tab seperated):

Hello,
I am pasting two tables of 6x4 and 4x4 together to get a 10x8 output. I want to fill the blank values with a NaN (Not a Number). How can I do this?
Thanks,

I have rrd file which is have the gaps and I want to fill it out with some value , I've got 10 NaN record and I try to populate data from 10 records be for NaN to change instead of NaN :(

Hello, I will like to delete/replace $3 with NaN. condition $3>-2000 (file1.dat) to produce out.dat. I want to retain the structure of the table. I use this code, this output only $3. Any idea on how to modify this code. Thank you.
