An interval is a range of real numbers, whose end points will be floats with at least 15 significant digits. The i command creates intervals, with the arguments in square brackets.
Examples.
[1.00000000000000..1.18181818181819] |
[1.73205080756886..3.14159265358980] |
Intervals can also be created by following a decimal number with a question mark. If the decimal number contains n digits, the interval will be centered at a and have width 2· 10−n.
Examples.
⎡ ⎣ | 0.121999999999999..0.124000000000000 | ⎤ ⎦ |
⎡ ⎣ | 0.789123454999990e3..0.789123456999998e3 | ⎤ ⎦ |
