Returns the ceiling for the time series described by the expression, by rounding any data values with decimals up to the nearest integer.

ceil() function returns the ceiling for each data value in the time series described by the expression.
The ceiling of a data value is the smallest integer that is greater than or equal to that value:
|Sample query with ceil()||Sample result||Input data value||Returned value (ceiling)|
| ||2||Positive, with fractional part||Next higher integer|
|-1||Negative, with fractional part||Integer part of the input value|
|1||Positive integer||Same as the input value|
|-1||Negative integer||Same as the input value|
ceil() returns a separate series of results for each time series described by the expression.
Here’s a query that returns a time series that reports positive fractional values between .2 and 1.2. The color has been changed to dark purple.
Now we apply
ceil() to our original query. Notice that the values below 1 are mapped to 1, and the values from 1 to 1.2 are mapped to 2. The the ceil function uses orange.
