Operators

At several places in EFDC_Explorer the user has the option of entering a value to replace the current value of some input parameter (e.g., bottom elevation) or to use an "operator". The latter is a simple mathematical function that will be applied to the current value of the parameter. A field that allows operators recognizes the inputs described in Table 3. Operators must be followed by a space then the value, unless it is a simple replacement value.
