Funktionsnavn:

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.

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.
