CAS: log of large integers?

[kharpster]

Unfortunately after playing around, at this point I cannot answer Joe's question, but I did determine the following:

Home Mode (default settings) "Limits" example:

log10(10^308) = 308
log10(10^309) = inf

LOG(ALOG(500)) = 500
LOG(ALOG(501)) = 500


CAS Mode (default settings) "Limits" example:

log10(10^307) = 307
log10(10^308) = inf

LOG(ALOG(308)) = 308
LOG(ALOG(309)) = inf
