Document Summary
Comments: /* this multi-line comment might typically set off a larger, block of code, and explain the function of the block *, // or you might just have a one-line comment like this. Put as a line by itself or in a line of code. Rounds down to and displays 6 decimal places: double. Rounds up to and displays 6 decimal places. Memory: if x and y are declared as int variables, they are two chunks of memory labeled as the names of the variables. Memory is serial, composed of four-byte words.
