I.8.2.2 Built-in value and reference types

The following data types are an integral part of the CTS and are supported directly by the VES. They have special encoding in the persisted metadata:

Table I.1: Special Encoding

Name in CIL assembler (see Partition II)	CLS Type?	Name in class library (see Partition IV)	Description
bool1	Yes	System.Boolean	True/false value
char1	Yes	System.Char	Unicode 16-bit char.
object	Yes	System.Object	Object or boxed value type
string	Yes	System.String	Unicode string
float32	Yes	System.Single	IEC 60559:1989 32-bit float
float64	Yes	System.Double	IEC 60559:1989 64-bit float
int8	No	System.SByte	Signed 8-bit integer
int16	Yes	System.Int16	Signed 16-bit integer
int32	Yes	System.Int32	Signed 32-bit integer
int64	Yes	System.Int64	Signed 64-bit integer
native int	Yes	System.IntPtr	Signed integer, native size
native unsigned int	No	System.UIntPtr	Unsigned integer, native size
typedref	No	System.TypedReference	Pointer plus exact type
unsigned int8	Yes	System.Byte	Unsigned 8-bit integer
unsigned int16	No	System.UInt16	Unsigned 16-bit integer
unsigned int32	No	System.UInt32	Unsigned 32-bit integer
unsigned int64	No	System.UInt64	Unsigned 64-bit integer

¹ bool and char are integer types in the categorization shown in the figure above.
