Specifies significant digits for the NONMEM report file.

 $FORMAT  FMTN=n ; (NM75)

 $FORMAT FMTN=3 ; (default) (NM75)

Display any significant digits for THETAs, OMEGAs, and SIGMAs results, and variance-covariance of estimates, listed in the NONMEM report file. The FMTN is the number of significant digits (which is by legacy and default 3), between 3 and 23. This also applies to $TABLE outputs to the NONMEM report file. The FORTRAN format will be formed as 1PE{FMTN+6}.{FMTN-1}. For example FMTN=6 will be 1PE12.5. If you wish G field format, set the FMTN to a negative value. For example FMTN=-4 will be 1PG10.3.

It is recommended that you place the $FORMAT record immediately after the $PROB record:

  $PROB My problem
  $FORMAT FMTN=5

This FMTN precision format will be in effect for outputs of all problems, until another $FORMAT record is given for a new $PROB in the control stream.
