Tr_float_can_branch_complex

-- Option variable: tr_float_can_branch_complex Default value: true

Tells the Maxima-to-Lisp translator to assume that the functions acos, asin, asec, and acsc can return complex results.

The ostensible effect of tr_float_can_branch_complex is the following. However, it appears that this flag has no effect on the translator output.

When it is true then acos(x) is of mode any even if x is of mode float (as set by mode_declare). When false then acos(x) is of mode float if and only if x is of mode float.

(%o1)                                true
