CALCULATEN

Metadata Instruction: Perform a calculation with a floating point output rounded off to 2 decimal places or type cast a string into a floating point output rounded off to 2 decimal places.

• When inserting a floating point into a variable
• When converting a number in string format into an actual floating point (i.e. type casting)
• For mathematical Operations such as additions, subtractions, multiplications, divisions
• For mathematical Operations where the operand is a number or a variable with a number in it

CALCULATEN evaluates a mathematical expression and stores the floating point output of the expression in another variable. If the output of the expression is a Float (a number with decimal places) with more than two decimal places, then output will be rounded off to two decimal places.

• DO NOT USE when you strictly need precision decimal places i.e, you don't want the floating point to be rounded off to 2 decimal places in the output. Use CALCULATENX instead.
• DO NOT USE when you strictly need integers for logics like Lane Count, Multistops etc. Use CALCULATENI instead.
• DO NOT USE in the root node.
• Use variables only if they have been previously declared.

CALCULATEN command is for node level operations. It can be used in any node as an instruction, except for the root node. It should not be used on the Arrows.

Let's take an example: CALCULATEN $output_variable "25.251 + 45.12"
Here, "$output_variable" is where the result of the expression "25.251 + 45.12" will be stored.
If you had a tree variable "$x1" which was previously initialized to 45.12, the above expression could have also been "25.251 + $x1"
