Answer 3

Floating points are decimals, period. Integers are round numbers.

Answer 4

Floating point numbers are decimal numbers (with fractional part) that are stored internally in a binary version of scientific notation. Integers cannot have a fractional part, and are stored in a sequence (usually the word size of the computer) of bytes. If a number with a fractional part is forced into an integer, the fractional part will be truncated.

Although floats can hold various numbers, they can't precisely hold many numbers. This can give some really flaky results for comparisons, and even for unformatted printing.
