Syntax Description Example
ACOS(fNumber) Returns the arccosine of number, for example, the angle (in radians) whose cosine is number.

ACOS(0)

Returns: PI/2

ANG360(fAngle) Normalizes an angle's range to be [0; 2PI). Angle is specified in radians. ANG360(1.4 + 2 * PI())
Returns: 1.4
ASIN(fNumber) Returns the arcsine of a number, for example, the angle (in radians) whose sine is number.

ASIN(1)

Returns: PI/2

ATAN2(fY,fX) Returns the angle (in radians) between the vector represented by x, y and the direction of the x-axis.

ATAN2(1,1)
Returns: PI/4

ATAN2(1,SQRT(3))
Returns: PI/6

ATAN(fNumber) Returns the arctangent of a number, for example, the angle (in radians) whose tangent is number. The resulting angle is in the range [-PI/2; PI/2]
