LOG(number, base)
- Where 'number' is the positive real number and
- '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 |
