Expression

Do your own calculations using simple expressions

Inputs

Inputs are automatically derived from the expression. An expression set to a + someName + 1 will get two inputs, one for a and one for someName.

Expression
The expression to be calculated

Outputs

Result
The result of running the expression

Built in math functions

Expressions support the following funcitons:

  • min(a,b) - Minimum of two values
  • max(a,b) - Maximum of two values
  • cos(angle) - The cosine of an angle in radians
  • sin(angle) - The sine of an angle in radians
  • tan(angle) - The tangent of an angle in radians
  • sqrt(a) - Square root of a number
  • pi - PI in radians
  • round(a) - Rounds a number to the closest integer
  • floor(a) - Removes the fractional part of a number
  • ceil(a) - Rounds a value up to the closest higher integer. E.g. round(1.1) equals 2.
  • abs(a) - The absolute value of a number. Negative values will become positive.
  • random() - A random number from 0 to 1

Advanced

The Expression node is running Javascript under the hood so in addition to the above functions any standard Javascript functions will also be valid. The Expression node will add a return statement before the expression is executed. 1+2 will be evaluated as return (1+2)
