I need to use the reduce method in JavaScript, since I need to sum the multiple concurrent values that are contained in an array.
As I'm using TypeScript (Ionic3), the types of these variables are number , not float or double .
When I run reduce with integers, everything works fine and returns the sum value.
But when I run a decimal value for example 10,00 + 10,00 it returns me NAN.
Is there any difference between making a% of decimal and integer values?
