Atan Function In Sql in SQL
? ATAN() Function in SQL
The ATAN() function returns the arctangent (inverse tangent) of a number. The result is given in radians.
? Syntax
ATAN(number)number: A numeric value.Returns a float representing the angle in radians.
? Examples
1. Arctangent of 1
SELECT ATAN(1);-- Returns approx 0.785398 (which is ?/4 radians)2. Arctangent of 0
SELECT ATAN(0);-- Returns 03. Convert to Degrees
SELECT ATAN(1) * 180 / PI() AS atan_degrees;-- approx 45 degrees? ATAN2() Variant
Some SQL databases provide ATAN2(y, x) which computes the arctangent of y/x taking into account the quadrant:
SELECT ATAN2(1, 1);-- Returns approx 0.785398 (?/4 radians)? Use Cases
Calculating angles from slope values.
Trigonometric computations in spatial and geometric queries.
?? Supported In
MySQL
PostgreSQL
SQL Server
Oracle
Want me to explain ATAN2() more or show how to use SIN(), COS() along with these?
