Returns the natural (base e) logarithm of a specified number
Class: Mathematical
Parameters: @d – A floating point number whose logarithm is to be found
Syntax: @returnValue=@log(@d)
Returns:
• If sign of @d is positive – The natural logarithm of @d
• If sign of @d is zero – Error
• If sign of @d is negative - Error
Remarks:
• Parameter @d is specified as a Base 10 number
• @log is the inverse of @exp
Example:
//Example for the mathematical @log method
@d=5.678 //Set value
@result=@log(@d) //Calculate result (= 1.7366)
message(“Log of “ + @d + “ is “ + @result) //Display results message
