  • Patent number: 9912796
    Abstract: The present disclosure provides a system and method for correcting an input number, the system comprising a memory having instructions stored thereon and at least one processor to execute the instructions to cause: obtaining and displaying an input number; detecting a user's error correction operation and expanding display areas of digits of the input number after the error correction operation is detected; receiving correction on the input number; wherein the receiving correction on the input number comprises: receiving a user's correction on the input number by a digit correction control, wherein the digit correction control is disposed at a position corresponding to the expanded display area of the respective digit; and the digit correction control is a digit-rolling control or a digit-increasing/decreasing control.
