Change formula parser to accept single operators as own expression
Last modified: 2013-02-07 22:38:01 UTC
For a limit to exist the left and right limits need to exist and have the same value. The formula to express this would be: lim csub{x %tendto 1 ^{-}}f(x) However the minus in brackets is treated as an operator and so it expects a value to follow. This may require a significant change to the parser to properly implement but adding a special character to the catalog may fix this: lim csub{x %tendto 1 ^{%leftbound}}f(x) Thus adding %leftbound (a negative sign) and %rightbound (a positive sign) may be sufficient.
As long as this is still not implemented, use an empty expression as workaround: lim csub{x %tendto 1 ^{-{}}}f(x) This is related to issue 87337.
