Detailed Description

A double option represents either an double or nothing.

Option types are typically used with functions that may return a value of the given type or nothing (i.e. the return value is optional). The none member is true if the value is not present. Otherwise the value can be accessed with the some member.

Example:

DoubleOption op = index_of_double_value(array, 0.5, EPSILON); // index of value 0.5?
if (op.none) {
    printsln("value not found");
} else {
    printdln(op.some);
}
