    Does anyone know if there is an inverse log function in Excel? I found a LOGINV function but it asked for parameters I'm not familiar with. I'm using a dB loss equation "dB = Log(Pout/Pin)*10" rearranged to calculate expected output power given the nominal dB loss and input power so I need to compute inverse log in the process. Thanks for any help on this.

    Hi Jeff,

    Use
    =EXP(exponent)
    to take the inverse of the natural logarithm.

    Use
    10^(exponent)
    or =POWER(10,exponent) to take the inverse base10 logarithm/

    HTH,
    Jay
