Is there any way to caculate log (to the base 10) using assembly language in '51?

Kai Klaas said:
Yes.

Assembler gives you complete, unencumbered, direct access to the processor's entire repertoire - so, if it couldn't be done in assembler, then it wouldn't be possible at all!

Whether it's practical or worthwile is an entirely different question...
