Stop trying to convert history values to ints (#555)

We would attempt to detect whether a extra history value was meant to be
an int or a float. But this was error prone with very large values.
Instead just treat everything as a float (given users can only provide
values in floats anyway this should not change peoples results).

Closes #354
