• 'base' is the base of the logarithm.

LOG() determines the logarithm of a number to the specified base.

Description

LOG(number, base)

For Example,

LOG(10, 2) returns 3.3219280948873626

LOG(100,10) returns 2

• The 'number' should be a positive real number. Else Calci displays NaN error message.
• The 'base' should be a positive real number. Else Calci displays NaN error message.
• If the 'base' is omitted, Calci assumes it to be 10.
• The function can be used to find the logarithm of array of numbers with a specified base.

e.g. LOG(10..15, 2) that displays the output as below -

number	base	LOG Output
10	2	3.3219280948873626
11	2	3.4594316186372977
12	2	3.5849625007211565
13	2	3.700439718141092
14	2	3.8073549220576037
15	2	3.9068905956085187
