Hi @brendanarnold, I'm running into this same bug.

In FORTRAN when I format a float with 0 precision, like "f6.0", I get the number with a decimal with no trailing numbers.

Example:

program printformat
implicit none

    real :: number

    number = 99999.01

    Print "(f6.0)", number

end program printformat

OUT: 
99999.

But in Python with fortranformt when I try the same formatting, I get ******

from fortranformat import FortranRecordWriter
record_line = FortranRecordWriter("f6.0")
record_line.write([99999.01])

OUT:
'******'

Which version are you using? I've tried to recreate locally and it seems to work

brendanarnold commented 2 years ago

Sorry, my bad that test was actually after I had applied some local changes - verified a bug

Fix is now in 1.1.0
