 @deftypefun int mpfr_fpif_import (mpfr_t @var{op}, FILE *@var{stream})
 Import the number @var{op} from the stream @var{stream} in a floating-point
 interchange format (see @code{mpfr_fpif_export}).
-The precision of @var{op} is read from the stream.
+Note that the precision of @var{op} is set to the one read from the stream,

 If the stored precision is zero or greater than @code{MPFR_PREC_MAX}, the
 function fails (it returns non-zero) and @var{op} is unchanged. If the
 function fails for another reason, @var{op} is set to NaN and it is
