    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.
    • If Number is less than or equal to 0, then LOG10 reports an invalid argument error (Fejl:502).

    • 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].
