Hello

Do we have math functions like Addition, multiplication in Modified Javascript. If we don’t have any functions like that how can we write custom script.

Hello Sridurga,

For math functions we have 2 steps in our process studio.  
1.Calculator  
2.Formula

Otherwise, we can use Modified Javascript for math functions using our own script in it, using javascript functions.
