No, Maxima doesn't have nothing quite like that. Likely, Maxima has the
tools to build such a function:
(1) float or bfloat with various values of fpprec (or maybe nfloat),
(2) rectform -- for complex values (float / bfloat don't always give a
rectangular form),
(3) random
(4) errcatch -- deal with overflow, divsion by zero, ...
(5) float_approx_equal and bfloat_approx_equal (undocumented, I think)
