-// One modification by macko in FormatScientific(): use 3 digits of exponent only if necessary (e+123), otherwise use two if necessary (e+45), otherwise use one (e+6)
+// One modification by macko in FormatScientific(): use 3 digits of exponent only if necessary (e+123), otherwise use two if necessary (e+45), otherwise use one (e+6).
 // This is consistent with java and javascript, and partially with python (which never uses one digit, only two or three).
+// To always print 3 digits in exponent (zero-padding if necessary), uncomment:
+// #define PRINTFLOAT_DRAGON4_ALWAYS_3_DIGIT_EXPONENT
