calculator-initial-operators is a variable defined in `calculator.el'.
Its value is shown below.

Documentation:
A list of initial operators.
This is a list in the same format as `calculator-operators'. Whenever
`calculator' starts, it looks at the value of this variable, and if it
is not empty, its contents is prepended to `calculator-operators' and
the appropriate key bindings are made.

This variable is then reset to nil. Don't use this if you want to add
user-defined operators, use `calculator-user-operators' instead.
