Floating-Point Arithmetic |
All the usual mathematical operations used in hand calculations have floating-point analogs that are used in computer-based calculations. |
However, some care is required when using the floating-point versions of mathematical operations because they do not follow the deeply engrained rules we all take for granted. |
For example, |
(2.5 - 2.4)/0.1 = 1.0000000000000008881...65625 |
while |
2.5/0.1 - 2.4/0.1 = 1.0000000000000035527...90625 |
