Doc editor:
The unit of measurement related to trigonometric functions is radian.
Thedafter numbers in the result is to indicate that the number is a double-precision floating point number.
TheRountfunction with two parameters will give strange results, and it's not solved.
It also includes other general purpose ones.
| Name | Description | Usage | Result |
|---|---|---|---|
| in | Returns whether an element is in a set of values. | in(1 + 1, 1, 2, 3) | true |
| if | Returns a value based on a condition. | if(3 % 2 = 1, 'value is true', 'value is false') | 'value is true' |
| ifs | Returns a value based on evaluating a number of conditions, returning a default if none are true. | ifs(foo > 50, "bar", foo > 75, "baz", "quux") | if foo is between 50 and 75 "bar", foo greater than 75 "baz", otherwise "quux" |
You can use comma,or semicolon;as argument separator.
Doc editor: You must use
,as argument separator in the Gigavolt Truth Table.
