[<Android.Runtime.Register("toUnsignedLong", "(S)J", "", ApiSince=26)>]
static member ToUnsignedLong : int16 -> int64

Parameters

x
Int16

the value to convert to an unsigned long

Returns

the argument converted to long by an unsigned conversion

Attributes

Remarks

Converts the argument to a long by an unsigned conversion. In an unsigned conversion to a long, the high-order 48 bits of the long are zero and the low-order 16 bits are equal to the bits of the short argument.

Consequently, zero and positive short values are mapped to a numerically equal long value and negative short values are mapped to a long value equal to the input plus 2<sup>16</sup>.
