 // =============> write your explanation here
+//The function has already declared the  decimalNumber variable. The same variable cannot be used or declared twice. 
+//The decimalNumber variable is only existing inside the the function. Therefore the console.log() will not have anything to print.
+//The decimalNumber must be called outside first.

 // Finally, correct the code to fix the problem
