Java is a very powerful programming language and offers a large and complex library. Only a small subset of the standard library is supported on the target to keep a small memory footprint and maintain a high performance.

The type long consists of 8 bytes and cannot be handled by the 32-bit architecture directly. Though all manipulations of this type are handled correctly by our compiler it is less efficient than working with 32 bit types where all basic calculations can be done in one clock cycle.
