atan({n})

Returns the arctan value of radians value {n}. {n} can be any real number in the range of -1e308 <= {n} <= 1e308. If null is passed as an argument, atan() returns null.

atan({n}) takes the following syntax.

SELECT ATAN(N) as ALIAS
FROM DATASET;

Example

This example takes the arctan of 90 degrees.

SELECT ATAN(RADIANS(90)) as arctanValue
FROM "Opportunity"
LIMIT 1;
