Hi Preeti,

It is unfortunate that in the USA a bar over a digit or digits is used in numbers after the decimal point to show that that digit or digit sequence recurs. In the UK we put a dot over the first and last digits of a recurring sequence in a decimal.

So we are making a different use of a bar over a digit here. We are following Tirthaji’s system, and in fact a bar over a digit makes sense as a negative as it is the same as a minus sign, only it goes on top.
