Only natural logarithm(of base e) is available under Math package of standard Java package version associated with Vijeo Designer software.
A workaround to calculate logarithm of base 10 is shown below:
Log base 10 = Math.log(x)/Math.log(10)
Log base 2 = Math.log(x)/Math.log(2)
Given a number n greater than 0.0.
Then the log10(n) is equal to ln(n)/ln(10)(where "ln()" is the natural logarithm (base e))
If you store ln(10) as a constant, then you can get the log10(n) from ln(n) with one additional divide.
Given a number 'n' greater than 0.0 and a number 'b'greater than 0.0
Then the log<b>(n) is equal to ln(n)/ln(b)
where log<b>(n) means log value of (n) on base 'b' and "ln( )" is the natural logarithm (on base 'e')
