Like Value, type, Pattern, var etc. in Value attribute the required value is been filled as per recommendation the other one we use Type this attribute used to specify that which kind of value will be formatted will it be Number, Currency or Percentage.

Here We made a program of <fmt: format Number> first we call the JSTL Library Code in the starting Of program and after then declaring a variable and assures the value we use some required attributes in given codes that will bring the Output as per their phase. Like we use grouping, Decimal place formatting like pattern and currency Mode also. And in the last we closed all the Html tags.
