%wg - Display Real

%wg is used for floating point values and has essentially the same effect as %wf (Display Real) unless the supplied value cannot adequately be represented in %wf form; in which case %wg has the same effect as %we (Display Real). To be specific, the %we form is only used if the exponent is less than -4 or greater than or equal the precision value. Note, however, that with %wg, trailing zeros after a decimal point are removed. Where appropriate, the decimal point is also removed.
