CALCULATENX

Metadata Instruction: Perform a floating point mathematical calculation with no rounding function applied or type cast a string into an floating point / decimal number with precision intact.
Edited By : Sobhit Sharma

• When inserting a float / decimal number into a variable with precision intact
• When converting a float / decimal number in string format into an actual float / decimal number (i.e. type casting)
• For precise mathematical operations such as additions, subtractions, multiplications & divisions as there is no rounding function applied
• For mathematical operations where the operand is a number or a variable with a number in it

CALCULATENX evaluates a mathematical expression and stores the output of the expression in another variable. There is no rounding function applied to the output of the mathematical calculation.

• 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.

CALCULATENX 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 as arrow text.

Let's take an example: CALCULATENX $output_variable "200.156 * (12 / 100)"
Here, "$output_variable" is where the result of the expression "200.156 * (12 / 100)" will be stored.
If you had a tree variable "$percent_rate" which was previously initialized to 12, the above expression could have also been "200.156 * ($percent_rate / 100)"
