LOG10
Kategori:
Matematisk
Resume:
Returnerer base 10-logaritmen af et tal.
Syntaks:
LOG10(Number)
Returnerer:
Returnerer et reelt tal, som er 10-talslogaritmen af tallet.
Argumenter:
Tallet er den positive, reelle værdi eller en reference til en celle, der indeholder det tal, hvis 10-talslogaritme skal beregnes.
- Hvis tallet er negativt eller 0, så returnerer funktionen en fejlværdi.
- If Number is less than or equal to 0, then LOG10 reports an invalid argument error (Fejl:502).
Yderligere oplysninger:
- For any positive real number x, [math]\displaystyle{ 10^{\text{log}(x)}=x }[/math] and [math]\displaystyle{ \text{log}(10^x)=x }[/math].
- To convert the common logarithm of a positive real number x to a natural logarithm (base-e), use the formula [math]\displaystyle{ \text{ln}(x)=\text{log}(x)~/~\text{log}(e) }[/math].
- Additional information about common logarithms can be found at Wikipedia's Common logarithm page.
