Number: nextULong(): reads an unsigned 64 bit number. note that the max precision in javascript is only 53 bits!
Number: nextInt(): reads a 32 bit signed number
Number: nextUInt(): reads a 32 bit unsigned number
Number: nextShort(): reads a 16 bit signed number
Number: nextUShort(): reads a 16 bit unsigned number
