             - Now the ir_dataset is initialized and since the ieee754_num list has the same element twice [ first is just the number and second is with sign ], hence we loop that array, considering only multiples of 2 elements from it. If the sign is ‘-’, then then the index is updated with 1 else if it is ‘+’, then it is updated with 0 complying with the IEEE standards.
             - The operand values are then passed into the extract_fields function to get individual fields in a floating point number (sign, exponent and mantissa).
             - Coverpoints are then appended with all rounding modes for that particular opcode.

 	Implementation:
             - The Sticky bit is calculated in each case. The guard bit here is always assumed to be zero and the sign is positive, so that miscalculation of the sticky bit will alter the final result.
-            - In the intermediate result dataset, the elements are appended as elements before the character ‘p’ and then the binary equivalent of ‘010’ + pow(2,i). 
+            - In the intermediate result dataset, the elements are appended as elements before the character ‘p’ and then the binary equivalent of ‘010’ + pow(2,i).
             - Finally on the extra bits, it is masked with the comment created in the previous point. All the first character of each element is converted to its floating point equivalent in a loop
             - The operand values are then passed into the extract_fields function to get individual fields in a floating point number (sign, exponent and mantissa).
             - Coverpoints are then appended with all rounding modes for that particular opcode.
