Calling it with no argument or two arguments is an error: log10() takes 1 argument, got 2.
Anything that isn't a number is an error: log10() needs a number, got text. Numeric text such as "0.5" is accepted.
Zero and negative numbers have no logarithm; the step stops with log10() has no result for that number.
