Can anyone explain what is going on here?

Why is the Floor() function producing a 3 in the following example?


logrange.sm (9 КиБ) скачан 38 раз(а).

Edit: The .sm shows it, but I am in 0.99.6671.

This appears to be more of an issue with the log() function perhaps?

like this: all maths functions are numerical approximations.
log(100000) does not come out exactly 4 [3 ± some epsilon]
just put log(10000.00000001) and get Floor [4]

floor(log(9999.999999999999))=4 [Mathcad]
floor(log(9999.999999999990))=3 [Mathcad]
floor(log(10000.00000001))=4 [Smath]
