You already know about integer arithmetic; now we will introduce some floating-point computations. There is nothing difficult here; a floating-point value has a decimal point in it and zero or more decimals. We have two kinds of floating-point numbers: single precision and double precision. Double precision is more accurate because it can handle more significant digits. With that information, you now know enough to run and analyze the sample program in this chapter.
Single vs. Double Precision
For those more curious, here is the story.
A single-precision number is stored in 32 bits: ...
