Block: Round/Floor/Ceiling

Type: io_math_round

Convert decimal numbers to whole numbers using different rounding strategies. Perfect for cleaning up sensor readings (23.7°F → 24°F), creating clean display values (3.14159 → 3), or preparing data for systems that only accept integers. Choose round for normal rounding, floor for always rounding down, or ceiling for always rounding up.

Fields

Operation

Choose how to convert your decimal to a whole number:

• Round: Standard rounding: 0.5 or higher rounds up, below 0.5 rounds down (e.g., 23.7 → 24, 23.4 → 23, 23.5 → 24). Best for general use and displaying clean values.
• Floor: Always rounds down to the nearest whole number, regardless of decimal value (e.g., 23.9 → 23, 23.1 → 23). Perfect for counting items, time calculations, or when you need conservative estimates.
• Ceiling: Always rounds up to the nearest whole number, regardless of decimal value (e.g., 23.1 → 24, 23.9 → 24). Great for capacity planning, ensuring minimum values, or safety margins.

Inputs

Value

The decimal number you want to convert to a whole number. Examples: sensor readings like 72.8°F, calculated values like 3.14159, or any numerical data that needs to be simplified. Non-numeric values will be automatically converted to numbers where possible.
