Math and Logic Nodes

Math and Logic nodes provide powerful computational and logical operations in ANDRON workflows, enabling complex data transformations and decision-making processes.

Comparison Node

The Comparison Node evaluates relationships between values, supporting multiple comparison types.

Configuration

• Comparison Type:
  • equals: Check strict equality
  • notEquals: Check inequality
  • greaterThan: Check if left value is greater
  • lessThan: Check if left value is less
  • greaterThanOrEqual: Check if left value is greater or equal
  • lessThanOrEqual: Check if left value is less or equal
  • typeOf: Check the JavaScript type of a value
  • instanceOf: Check object instance type

Example

{
  "type": "comparison",
  "name": "Age Validation",
  "leftOperand": "{{user.age}}",
  "rightOperand": 18,
  "comparisonType": "greaterThanOrEqual",
  "returnType": "boolean"
}

Use Cases

• Data validation
• Age restrictions
• Type checking
• Conditional routing

Mathematical Operation Node

Perform arithmetic and advanced mathematical computations.

Configuration

• Operation Type:
  • add: Addition
  • subtract: Subtraction
  • multiply: Multiplication
  • divide: Division
  • modulo: Remainder calculation
  • power: Exponentiation
  • sqrt: Square root
  • abs: Absolute value
  • round: Rounding
  • floor: Floor value
  • ceiling: Ceiling value

Example

{
  "type": "math",
  "name": "Price Calculation",
  "operation": "multiply",
  "operands": ["{{product.basePrice}}", "{{product.quantity}}"],
  "roundTo": 2
}

Use Cases

• Financial calculations
• Inventory management
• Scientific computations
• Dynamic pricing

Boolean Logic Node

Perform complex logical operations combining multiple conditions.

Configuration

• Logic Type:
  • and: Logical AND (all conditions must be true)
  • or: Logical OR (at least one condition true)
  • not: Logical NOT (invert a condition)
  • xor: Exclusive OR (exactly one condition true)

Example

{
  "type": "boolean",
  "name": "User Access Check",
  "logicType": "and",
  "conditions": [
    {
      "type": "comparison",
      "leftOperand": "{{user.isVerified}}",
      "rightOperand": true
    },
    {
      "type": "comparison",
      "leftOperand": "{{user.role}}",
      "rightOperand": "admin"
    }
  ]
}

Use Cases

• Complex authorization checks
• Multi-condition validation
• Advanced filtering
• Permission management

Error Handling

• Nodes provide detailed error messages for invalid operations
• Type coercion and strict type checking
• Configurable error handling strategies
• Comprehensive logging of computational steps

Performance Considerations

• Optimized for high-performance computational tasks
• Minimal overhead for simple operations
• Efficient memory management
• Configurable precision for floating-point calculations

Security Notes

• All input values are sanitized before computation
• Prevent potential injection or unexpected type conversion
• Configurable type strictness
• Secure handling of mathematical edge cases

Advanced Features

• Support for dynamic operand resolution
• Template string interpolation
• Complex nested condition support
• Configurable error tolerance
• Extensible through custom computation plugins

Precision and Limitations

• Default floating-point precision: 15 decimal places
• Large number support up to JavaScript's Number.MAX_SAFE_INTEGER
• BigInt support for extended numerical range
• Configurable rounding and precision modes
