Does Java read integers in little endian or big endian?
...or least significant byte.
Endianness is not bit based but byte based.
To convert from unsigned byte to a Java integer:
int i = (int) b & 0xFF;
To convert from unsigned 32-bit little-endian in byte[] to Java long (from the top of my head, not tested):
long l = (long)b[0] & 0xFF;
l += ((...

What is an alternative to execfile in Python 3?
... is better, since it takes the globals and locals from the caller:

C# short/long/int literal format?
...als 1m, 1.5m, 1e10m, and 123.456M are all of type decimal. This literal is converted to a decimal value by taking the exact value, and, if necessary, rounding to the nearest representable value using banker's rounding (Section 4.1.7). Any scale apparent in the literal is preserved unless the value i...
