Try something more like:
Note, however, that $1/$2 is always going to be zero when $1 is a string that starts with non-numeric characters (other than a few magic strings like Infinity and NaN).

ctanhf
CTANH(3) BSD Library Functions Manual CTANH(3)NAME
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.
