Expression

Updated: 8 Apr 2024

Evaluates an expression using input modifier values.

Method #

This node evaluates an expression and outputs its value. The node can have up to four input values.

Available functions #

Symbol	Description
Sin	Sine
Cos	Cosine
Tan	Tangent
ASin	Inverse Sine
ACos	Inverse Cosine
ATan	Inverse Tangent
Sqrt	Square Root
Log	Logarithm
Log10	Logarithm Base 10
Exp	Exponential
Abs	Absolute
Factorial	Factorial

Available operators #

Symbol	Description
+	Add
-	Subtract
*	Multiply
/	Divide
^	Power
%	Modulus
()	Bracket

All trigonometry functions use radians, not degrees.

Example expressions #

Value0 * Value1

(Value0 + Value1) / Value2

(Value0 / Value1) ^ 2

Value0 * Sin(Value1) + Exp(Value2)

Factorial(Value0)

// Converts radians to degrees
Value0 * (3.14159265 / 180)

The output is a numeric value that can be further processed with other modifiers, or directly connected to a parameter in another node, using the operation method selected.

These properties control the core behaviours of the node.

Parameter	Details
Current Value	Shows the resulting value of the expression. Cannot be directly changed.
Expression	The text expression (see Example expressions above)
Value0-3	Values to be used in expression
Modifier Operation	The operation to be performed on the targeted parameter. Add : Adds to the parameter value. Subtract : Subtracts from the parameter value. Multiply : Multiplies the parameter value. Replace : Replaces the parameter value.
