I have a system of equations that returns a RealRange :

xLp_tmp := RealRange(85.32914119, infinity)

it actually looks like this:
 

anyway, I want to "pick" the lowerbound of that range and assign it to a variable but I can't figure  out how to do it.  

I've tried:

xLp_tmp[1] 

lowerbound(xLp_tmp)

but neither worked.  I don't know what else to try.

Thank you in advance for the help.
