The ISC currently accepts either floating point expressions or
correct Maple syntax as input. However, for Maple syntax requiring too
long for evaluation, a timeout has been implemented.
Factors of ten (and decimal points) are ignored in the input: you should
check the results and rescale as required.

The Inverse Symbolic Calculator (ISC) uses a combination of lookup tables and
integer relation algorithms in order to associate a closed form representation with
a user-defined, truncated decimal expansion (written as a floating point expression).
The lookup tables include a substantial data set compiled by S. Plouffe both before
and during his period as an employee at CECM.

The ISC is down for maintenance indefinitely.
