FARRE Posts: 5 Rating: (0)	Hello, i'm trying to convert a real number between (0,0005 and 1000 mbar -from a pressure probe- to an exponential notation (with sign+mantissa+exponent)? Can anyone help me. Thanks.

This piece of information will be available in STEP 7 offline help itself, you can press F1 and serach for REAL data type to get this. But why do you need to seperate this any specific reason you have?
