Summary:  question from limit involving a float

Initial Comment:
The limit code has far too much  code that fills the fact data base with  comparisons to 1.0*10^8 or
1.0*10^-8. One of these silly facts leaks out:

(%i16) integrate( t*exp(-(t-a)^2), t)$

Silly question:

(%i17) limit(%,t,minf);
"Is  "t+a+1.0*10^8"  positive or negative?"neg;
(%o17) 0

(%i18) build_info();
