Not at the moment.  tlibm only handles math functions with
a single real agrument [1].  I've been thinking about adding
the 2 argument functions such as atan2 and complex argument
function, but lack the time.  I also need to improve the man
page to decoment the default domain for each function and its
complete domain.

[1] acos, acosh, asin, asinh, atan, atanh, cbrt, cos, cosh, erf,
    erfc, exp, exp2, expm1, j0, j1, lgamma, log, log10, log1p,
    log2, sin, sinh, sqrt, tan, tanh, tgamma, y0, y1.
