I assume you are talking about a floating point chip. This will not
affect the performance of eroff unless you are using pic or grap.
Troff, nroff, tbl and eqn basically use integer arithmetic only.
Pic and grap use floating point extensively. The printer drivers
only use floating point where it is necessary for the floating point
output of pic and grap. Therefore an FP chip will not help you
if you are only using tbl and eqn.
