Numeric Types and Literals
U-SQL’s built-in numeric types are:
byte byte? sbyte sbyte? int int? uint uint? long long? ulong ulong? float float? double double? decimal decimal? short short? ushort ushort?
The grammar rules use Numeric_Type to refer to one of these types.
They follow the C# rules regarding ranges and how they treat literals. For more information see Types (C# Reference).
