Struct `std.int128.Int128`

128 bit signed integer type.


						
				struct Int128
				;

Constructors

Name	Description
`this` (lo)	Construct an `Int128` from a `long` value. The upper 64 bits are formed by sign extension.
`this` (lo)	Construct an `Int128` from a `ulong` value. The upper 64 bits are set to zero.
`this` (hi, lo)	Construct an `Int128` from a `long` value.
`this` (data)	Construct an `Int128` from a `Cent`.

Fields

Name	Type	Description
`data`	`core.int128.Cent`	core.int128.Cent

`opCast` ()	Support casting to a bool
`opCast` ()	Support casting to an integral type
`opCast` ()	Support casting to floating point type
`opCmp` (op2)	support arithmentic comparison operators < <= > >=
`opEquals` (lo)	Compare for equality
`opEquals` (lo)	Compare for equality
