My variable x is double precision. (ex: x=3.87768554688)
I want write it with 6 digits after the decimal and do not use scientific notation.
I have tried format (F8.6). But it gives this message:

Error 51: Format/ data mismatch


What should I use to write x with 6 digits after the decimal and do not use scientific notation.

write(*, 900) x

900 format (????)

x=3.877685

Hi

try using f10.6 or f12.6 or more, depending on what number you have

If you use F8.6 you can only write numbers with 1 digit before the decimal ( e.g. 4.123456 )
If you try to write e.g. 12.123456 or -3.123456 you will get this error.

Although Klaus is correct in saying that you should allow enough characters in the field width, failure to do so does not cause this runtime error.

The following code is "successful" but outputs a row of stars...

real(2) x
x = 2222222.122344
write(*,900)x
900 format(f8.6)
end

A data mismatch would occur if, for example, you declared x as an INTEGER.
