-				Easing function, based on exponent. The curve values are: 0 is constant, 1 is linear, 0 to 1 is ease-in, 1+ is ease out. Negative values are in-out/out in.
+				Returns an "eased" value of [code]x[/code] based on an easing function defined with [code]curve[/code]. This easing function is based on an exponent. The [code]curve[/code] can be any floating-point number, with specific values leading to the following behaviors:
+				[codeblock]
+				- Lower than -1.0 (exclusive): Ease in-out
+				- 1.0: Linear
+				- Between -1.0 and 0.0 (exclusive): Ease out-in
+				- 0.0: Constant
+				- Between 0.0 to 1.0 (exclusive): Ease in
+				- 1.0: Linear
+				- Greater than 1.0 (exclusive): Ease out
