Study Notes

Blockly Math Operations

  • Blockly provides blocks for various mathematical operations.
  • Basic Arithmetic:
    • Uses Number Blocks for inputting numerical values.
    • Includes Operator Blocks for:
      • Addition (+)
      • Subtraction (-)
      • Multiplication (*)
      • Division (/)
    • To calculate 5 + 3: Drag a "Math Number" block, set value to 5. Drag another "Math Number" block, set value to 3. Drag a "Math Operation" block and select "+". Connect the number blocks to the input ports of the "+" operator block.
  • Advanced Math Functions:
    • Often includes:
      • Trigonometric functions (sin, cos, tan, asin, acos, atan)
      • Logarithmic functions (log, ln)
      • Exponential functions (pow, sqrt)
      • Rounding functions (round, ceil, floor)
    • To calculate the square root of 16: Drag a "Math Number" block, set value to 16. Drag a "Math Function" block and select "sqrt". Connect the number block to the input of the "sqrt" function.
  • Variables:
    • Store numbers in variables using "set variable" blocks.
    • Use variables in mathematical expressions.
  • Important Considerations:
    • Verify the specific Blockly version for available blocks and functions.
    • Break complex calculations into smaller steps for better clarity.
    • Thoroughly test your Blockly scripts for accurate results.
    • Drag a "Math Number" block, set its value to the desired number, and connect it to the function's input port.
