BooleanToNumber

The BooleanToNumber operator converts BooleanData messages to NumberData messages. Each boolean value is mapped to a numeric equivalent: true becomes 1.0 and false becomes 0.0. Timestamps are preserved.

Configuration

Requires only an operator ID.

Ports

• Input Port 0: Accepts BooleanData messages
• Output Port 0: Emits NumberData messages

Example Operation

Time	Input Port 0 (Boolean)	Output Port 0 (Number)
1	true	1.0
2	false	0.0
3	true	1.0
5	false	0.0
7	true	1.0

Behavior

The BooleanToNumber operator:

• Maintains message order
• Preserves timestamps
• Does not buffer messages
• Has constant 1:1 throughput
• Maps true to 1.0 and false to 0.0

Mathematical representation: $y(t_n) = \begin{cases} 1.0 & \text{if } x(t_n) = \text{true} \\ 0.0 & \text{if } x(t_n) = \text{false} \end{cases}$

Implementation

// Create operator
auto b2n = make_boolean_to_number("b2n1");

// Process boolean values
b2n->receive_data(create_message<BooleanData>(1, BooleanData{true}), 0);
b2n->receive_data(create_message<BooleanData>(2, BooleanData{false}), 0);
b2n->execute();

// Output will contain NumberData messages: 1.0 at time 1, 0.0 at time 2

Error Handling

Throws std::runtime_error if:

• Receiving message with incorrect type
• Receiving message on invalid port
