Represents the initial value of a number field, displayed before the user has entered an explicit value.
An unchanging initial value can be assigned to a number field simply by typing a value in the field in Calcapp Creator.
When a field is reset through a reset button, its value is set to the initial value (unless the reset button has been configured to instead assign blank values).
If an initial value is set through a formula, the formula is evaluated just before the screen housing the field is shown. In other words, the formula can reference values of fields that have been shown previously.
