Hi Wen-Long,

I'm not very familiar with Fortran, but to me this
looks like just the D notation for DOUBLE PRECISION
type, i.e. 8D0 = 8. 10^0 = 8. etc.

You can disable it using the FortranDoublePrecision option:

Write2["sang.abc", abc = 0.6*(-8 + 12 Log[5 + y[1]]),
 abc1 = 1/x^(2/3), FormatType -> FortranForm,
 FortranFormatDoublePrecision -> False]

which returns

        abc = 0.6*(-8. + 12.*Log[5. + y[1.]])
        abc1 = x^(-0.6666666666666666)

Cheers,
Vladyslav
