1. What is Mixed to Whole Number Conversion?

Mixed to whole number conversion truncates a mixed number (a number with both whole and fractional parts) to its whole number component by removing the fractional part.

2. How Does the Calculator Work?

The calculator uses the floor function:

Where:

• \( \text{mixed} \) — Any real number (positive or negative)
• \( \text{floor} \) — Mathematical function that returns the largest integer less than or equal to the input

Note: This is different from rounding - it simply removes the fractional part without changing the whole number.

3. Practical Applications

Details: This conversion is useful in programming, financial calculations where fractional units aren't allowed, and any situation requiring integer-only values.

4. Using the Calculator

Tips: Enter any real number (positive or negative) and the calculator will return the whole number portion by truncating the decimal part.

5. Frequently Asked Questions (FAQ)

Q1: How is this different from rounding?
A: Rounding may change the whole number (e.g., 4.6 rounds to 5), while truncation always keeps the whole number part (4.6 becomes 4).

Q2: What about negative numbers?
A: The floor function works the same way - -3.7 becomes -4 (the next lower integer).

Q3: When should I use this instead of rounding?
A: Use when you need to count complete units (like items you can't divide) or when programming requires integer values.

Q4: Is this the same as integer division?
A: Conceptually similar, but integer division applies to division operations while this applies to any number.

Q5: What's the difference between floor() and ceil()?
A: floor() goes to the lower integer, ceil() goes to the higher integer (e.g., floor(4.3)=4, ceil(4.3)=5).
