Arc Tangent node

Access: Nodes > Math > Arc Tangent

Returns the angle whose tangent is the input. Output is always in the range −π/2 … +π/2. No domain restrictions — safe for any input. This node is helpful for high-contrast gradient softening.

Input (RGB)	Output (RGB
0.0, 0.0, 0.0	0.0, 0.0, 0.0
1.0, 1.0, 1.0	0.7854, 0.7854, 0.7854
100.0, 100.0, 100.0	1.5608, 1.5608, 1.5608

Arc Tangent node inputs

Input
