(Engine-Level Function)
| Description: | Returns the trigonometric arc tangent in radians. |
| Returns: | Numeric |
Usage:  |
Script or steady state. |
| Function Groups: | Trigonometric Math |
| Related to: | ACos | ASin | Cos | Sin | Tan |
| Format: |
ATan(X) |
| Parameters: |
| X |
| Required. Any numeric expression. |
| Comments: |
The returned angle is in radians. To convert an angle from radians to degrees, divide by \Pi / 180 or (approximately) 0.0174533. (\Pi is a defined constant in VTScada.) This function does calculations with double-precision floating point values and does not support 64-bit integers computations. |
Example:
RadAngle = ATan(1); DegAngle = RadAngle / \Pi / 180;
The value of DegAngle will be 45.
