Log10(number)
Description
Log10 returns the base-10 logarithm of a number. The required parameter, number, is any numeric expression.
Example (Basic)
Rem Log10 Example 'Log10 calculates natural logarithms Dim e e = 2.718282 Print "Log10(20) = " & Log10(20) Print "Log10(25) = " & Log10(25) Print "Log10(100) = " & LogN(10, 100) Function LogN(Base, Number) LogN = LOG(Number) / LOG(Base) End Function
Output
Log10(20) = 1.301029996 Log10(25) = 1.397940009 Log10(100) = 2
