Description |
|---|---|
byte : System.Nullable<'T> -> System.Nullable<byte> |
Converts the argument to nullable byte, Nullable<byte>. This is a direct conversion for all primitive numeric types. The operation requires an appropriate static conversion method on the input type. |
char : System.Nullable<'T> -> System.Nullable<char> |
Converts the argument to a nullable character, Nullable<char>. Numeric inputs are converted according to the UTF-16 encoding for characters. The operation requires an appropriate static conversion method on the input type. |
decimal : System.Nullable<'T> -> System.Nullable<System.Decimal> |
Converts the argument to a nullable decimal, Nullable<Decimal> using a direct conversion for all primitive numeric types. The operation requires an appropriate static conversion method on the input type. |
enum : System.Nullable<'T> -> System.Nullable<'U when 'U : enum> |
Converts the argument to a particular nullable enum type. |
float : System.Nullable<'T> -> System.Nullable<float> |
Converts the argument to a nullable 64-bit float, Nullable<float>. This is a direct conversion for all primitive numeric types. The operation requires an appropriate static conversion method on the input type. |
float32 : System.Nullable<'T> -> System.Nullable<float32> |
Converts the argument to a nullable 32-bit float, Nullable<float32>. This is a direct conversion for all primitive numeric types. The operation requires an appropriate static conversion method on the input type. |
int : System.Nullable<'T> -> System.Nullable<int> |
Converts the argument to nullable signed 32-bit integer, Nullable<int>. This is a direct conversion for all primitive numeric types. The operation requires an appropriate static conversion method on the input type. |
int16 : System.Nullable<'T> -> System.Nullable<int16> |
Converts the argument to a nullable signed 16-bit integer, Nullable<int16>. This is a direct conversion for all primitive numeric types. The operation requires an appropriate static conversion method on the input type. |
int32 : System.Nullable<'T> -> System.Nullable<int32> |
Converts the argument to a nullable signed 32-bit integer, Nullable<int32>. This is a direct conversion for all primitive numeric types. The operation requires an appropriate static conversion method on the input type. |
int64: System.Nullable<'T> -> System.Nullable<int64> |
Converts the argument to a nullable signed 64-bit integer, Nullable<int64>. This is a direct conversion for all primitive numeric types. The operation requires an appropriate static conversion method on the input type. |
nativeint : System.Nullable<'T> -> System.Nullable<nativeint> |
Converts the argument to a nullable signed native integer, Nullable<nativeint>. This is a direct conversion for all primitive numeric types. Otherwise the operation requires an appropriate static conversion method on the input type. |
sbyte : System.Nullable<'T> -> System.Nullable<sbyte> |
Converts the argument to a nullable signed byte, Nullable<sbyte>. This is a direct conversion for all primitive numeric types. The operation requires an appropriate static conversion method on the input type. |
uint16: System.Nullable<'T> -> System.Nullable<uint16> |
Converts the argument to a nullable unsigned 16-bit integer, Nullable<uint16>. This is a direct conversion for all primitive numeric types. The operation requires an appropriate static conversion method on the input type. |
uint32 : System.Nullable<'T> -> System.Nullable<uint32> |
Converts the argument to a nullable unsigned 32-bit integer, Nullable<uint32>. This is a direct conversion for all primitive numeric types. The operation requires an appropriate static conversion method on the input type. |
uint64 : System.Nullable<'T> -> System.Nullable<uint64> |
Converts the argument to a nullable unsigned 64-bit integer, Nullable<uint64>. This is a direct conversion for all primitive numeric types. The operation requires an appropriate static conversion method on the input type. |
unativeint : System.Nullable<'T> -> System.Nullable<unativeint> |
Converts the argument to a nullable unsigned native integer, Nullable<unativeint>, using a direct conversion for all primitive numeric types. Otherwise, the operation requires an appropriate static conversion method on the input type. |
