Siunitx: Wrong parse in S-column tabular












3















Multiple uses of a text file containing numbers include a representation in a table. I read the file line by line and save those in a macro for a later use in a table. I use the S-column specifier of siunitx to format those numbers. Unfortunately, the occasionally present exponents are not parsed, i.e. the mantissa is parsed, but the exponents still remain in the output with some space.



If I explicitely use num{line} instead, all is done perfectly (except, commas are not placed below each other). So, what's wrong here?

          You should use read and not readline, which assigns the wrong category code to e. You also had many spurious spaces in the preparetable macro definition.
