ValueTypes

SDLang's datatypes map to D's datatypes as described below. Most are straightforward, but take special note of the date/time-related types.

Boolean:                       bool
Null:                          typeof(null)
Unicode Character:             dchar
Double-Quote Unicode String:   string
Raw Backtick Unicode String:   string
Integer (32 bits signed):      int
Long Integer (64 bits signed): long
Float (32 bits signed):        float
Double Float (64 bits signed): double
Decimal (128+ bits signed):    real
Binary (standard Base64):      ubyte[]
Time Span:                     Duration

Date (with no time at all):           Date
Date Time (no timezone):              DateTimeFrac
Date Time (with a known timezone):    SysTime
Date Time (with an unknown timezone): DateTimeFracUnknownZone
