perhaps I'd better state what I'm doing.
i have an array of 4 bytes and a want to convert them to a 32

and convert the 32 bit int back into a 4 bytes again.
Small hack I use in Dakka:
union RawConvTypes(T) {
T value;
ubyte[T.sizeof] bytes;
ubyte[T.sizeof] opCast() {
return bytes;
}
}
auto iRCT = RawConvTypes!int(5);
assert(iRCT.bytes == [5, 0, 0, 0]);
Can be quite useful for evil conversions.
But as I understood the OP, he want's to use the bytes as decimal
digits, i.e.
assert(my_convert([4,7,0,1]) == 4701);
Reinterpret casting will not do this...
