GObject.UInt64

GObject.UInt64 represents the guint64 type in the GObject type system. You can pass this class object to methods taking a GObject.Type.

A guint64 value is an integer numeric value between 0 and 18446744073709551615, that is, an unsigned 64 bit number.

Note that because JS represents numbers in the double-precision floating point format, which only has 52 significant bits, converting to and from guint64 may result in loss of precision.

Creating a new object with new GObject.UInt64 returns a Number object with value 0.

Calling GObject.UInt64(arg) will coerce the argument to a number.
