R has numerical values up to about 1e308 (10^308), but you have not told 
us your matrix size.  It sounds as if you would benefit from  re-scaling 
your matrix and problem.

Read the help page (as the posting guide asked you to)?  It mentions 
determinant() which will give you the value on log scale.
