Perhaps if you check the manual, you can find the function you need.

Thanks for the most obvious non helpful comment. I know it's a log function but, I'm having an issue trying to convert it to log that's why I'm asking for help in the "PHP Coding Help" forum.

 

[Need help with Natural Log]

I need help with these 3 formulas. Since PHP doesn't accept the LN function. I appreciate the help.

 

              1.162*ln('PREBUN'/'POSTBUN') 
 

              -ln(('POSTBUN'/'PREBUN)-(0.008*('TIME'/60)))+((4-(3.5*'POSTBUN'/'PREBUN'))*'UFVOL'/'POSTWEIGHT')

 

              ln('PREBUN'/'POSTBUN')
