[Clp] Floating Point Exception Resolved

[Sebastian Theophil]

Hi,

I took a further look at the floating point exception problem described
in my previous mail. 

First of all, the exception itself is of course not Clp's problem but is
triggered by setting the FPU exception status. Second, if no exception
is triggered, 1.0e5/0.0 will be +INFINITY and thus

double useError = CoinMin(largestPrimalError_,
 
1.0e5/maximumAbsElement(solution_,numberRows_+numberColumns_));  

useError will be largestPrimalError_

Thus, Clp handles the case correctly. 

Regards
Sebastian
