longFrom
Convert 8 bytes from source ByteArray, starting at index offset, to a Long.
e.g.
val source = 9223372034707292160L
val dest = ByteArray(8) { -100 }
println(dest.toList())
// [-100, -100, -100, -100, -100, -100, -100, -100]
Endian.Big.pack(source, dest, 0)
println(dest.toList())
// [127, -1, -1, -1, -128, 0, 0, 0]
println(Endian.Big.longFrom(dest, 0))
// 9223372034707292160
dest.fill(-100)
Endian.Little.pack(source, dest, 0)
println(dest.toList())
// [0, 0, 0, -128, -1, -1, -1, 127]
println(Endian.Little.longFrom(dest, 0))
// 9223372034707292160Content copied to clipboard
