Formula Explanation for Float Calculator
The Float Calculator uses standard arithmetic formulas depending on the selected operation.
1. Addition Formula
Result = Number1 + Number2Example:
12.5 + 7.3 = 19.82. Subtraction Formula
Result = Number1 - Number2Example:
15.75 - 5.25 = 10.53. Multiplication Formula
Result = Number1 × Number2Example:
4.5 × 2.5 = 11.254. Division Formula
Result = Number1 ÷ Number2Example:
20 ÷ 4 = 5⚠️ Note: Division by zero is not allowed as it results in an undefined value.
