The result appears as follows in the interface: Only four parameters are entered for the Mult node-the alpha and depth parameters are omitted. Therefore, the alpha and depth parameters default to a value of 1. You can also see that Mult looks for two types of data: An image (labeled In) and floats (labeled red, green, blue, and so on.). A float is any number that contains a decimal place, for example, 1.2, 10.00, .00001, or 100,000.00. The following table lists the five types of data. Data Type image float int string curve float or curve int Description An image. A number with a decimal place, such as .001, 1.01, or 10,000.00. Integer. A number with no decimal place, such as 0, 1, or 10,000. "this is a string" A special case of float or int that designates that the number has the possibility of being changed during script execution or when tuning it in the interface. Shake is usually smart enough to convert an integer into a float, so when the following is entered: MaryAnn = Mult(Lovey, 1, 1, .2); Shake does not freak out that you enter two integers (1, 1) for the red and green multipliers. However, this is an infrequent case concerning the conversion of floats and integers, as you cannot put in a string or an image for those arguments. For example: MaryAnn = Mult(Lovey,"1", Gilligan, .2); 956 Chapter 31 Expressions and Scripting
