Need to know how to use log function in PI calc formula. I was trying to calculate LMTD for an exchanger with

Formula  = (((Hotside in -Cold Side Out))-((Hotside out -Cold Side in)))/(LN(((Hotside in -Cold Side Out))/((Hotside out -Cold Side in))))

Here the LN is available in excel but could not use in PI calc. Any one has idea how to configure this is PI calc formula ?
