<p>It is provided a method, an apparatus, and a system for processing a numerical value in sending information using sound waves. The method mainly includes: generating intermediate values from the numerical value which is to be converted into a short link, wherein a number of the intermediate values is equal to a number of characters included in the short link, the numerical value and the short link have a relationship as 10.^(M-1) < X.^N; obtaining characters each corresponding to a respective one of the intermediate values from a preset mapping table between the intermediate values and the characters; joining together the characters to obtain the short link; and transmitting the obtained short link using sound waves. Therefore, the application range of sending information using sound waves can be extended, and the usage of sending information using sound waves can be enhanced.</p> |
