Dear D. Labes!

❝ spreedsheets […] use the function log() for that and eventually log10() for the logs to base 10.

Not quite. M$-Excel, OpenOffice-Calc:
LN(EXP(1)) natural (Napierian)
LOG10(10^1)) decadic
LOG(10^1)) no base given, fallback to decadic
LOG(10^1,10)) base 10, same as LOG10()
LOG(2^1,2) base 2 (logarithmus dualis)
LOG(PI()^1,PI()) crazy, but working
