| ANSI Common Lisp 22 Printer 22.3 Formatted Output 22.3.3 FORMAT Floating-Point Printers ### 22.3.3.3 Tilde G: General Floating-Point The next arg is printed as a float in either fixed-format or exponential notation as appropriate. The full form is `~w,d,e,k,overflowchar,padchar,exponentcharG`. The format in which to print arg depends on the magnitude (absolute value) of the arg. Let n be an integer such that 10n-1 <= |arg| < 10n. Let ee equal e+2, or 4 if e is omitted. Let ww equal w-ee, or nil if w is omitted. If d is omitted, first let q be the number of digits needed to print arg with no loss of information and without leading or trailing zeros; then let d equal `(max q (min n 7))`. Let dd equal d-n. If 0 <= dd <= d, then arg is printed as if by the format directives `~ww,dd,,overflowchar,padcharF ee@T` Note that the scale factor k is not passed to the `~F` directive. For all other values of dd, arg is printed as if by the format directive `~w,d,e,k,overflowchar,padchar,exponentcharE` In either case, an `@` modifier is supplied to the `~F` or `~E` directive if and only if one was supplied to the `~G` directive. `~G` binds *print-escape* to false and *print-readably* to false.
