The default (free-form) formats are G13.6 for FLOATs and G16.8 for
DOUBLEs. If you need more places to the right of the decimal point, you
have to use an explicit format. (Building IDL Applications, v. 5.6, p.
234)

"G - Use F or E format depending on the magnitude of the value being
processed."

IDL> d = 98046763.617D
IDL> print, d, FORMAT = "(G16.8)"
98046764.
IDL> print, d, FORMAT = "(F20.8)"
98046763.61700000
IDL> print, d, FORMAT = "(E20.10)"
9.8046763617E+07
