Stack effect: ( a -- n )

Read the value at a memory address.

In Haiku Forth, only 16 memory locations 0-15 are provided. Fractional addresses, are floored. Out of bounds addresses are wrapped. While accessible from each pixel location, only values stored when x=0,y=0 are persisted to the next frame. NOTE: The memory layout of Haiku Forth may change in the future. Do not rely on wrap around.

NOTE: In Haiku Forth (unlike Traditional Forth), all stack cells and memory locations are floating point numbers.
