1. What is Decimal Notation?

Decimal notation is a way of writing numbers that uses base 10 and includes a decimal point to separate the integer part from the fractional part. It's the most common way to represent numbers in everyday mathematics.

2. How Does the Calculator Work?

The calculator converts various number formats to decimal notation:

• Fractions: Converts fractions (like 3/4) to decimal (0.75)
• Percentages: Converts percentages (like 75%) to decimal (0.75)
• Scientific notation: Converts scientific notation (like 7.5e-1) to decimal (0.75)

3. Importance of Decimal Notation

Details: Decimal notation is fundamental in mathematics, science, and everyday calculations. It provides a standardized way to represent fractional quantities and is essential for precise calculations.

4. Using the Calculator

Tips: Enter your number in the original format, select the notation type you're converting from, and click "Convert". The calculator will display the decimal equivalent.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between decimal and fraction?
A: Fractions represent numbers as ratios (3/4), while decimals represent the same value in base 10 (0.75). Some numbers have exact fraction representations but repeating decimal ones.

Q2: How precise are the conversions?
A: Conversions are precise to 6 decimal places. For fractions, exact decimal representations are shown when possible.

Q3: Can I convert decimal back to other formats?
A: This calculator currently only converts to decimal. Future versions may include reverse conversions.

Q4: What about very large or small numbers?
A: The calculator handles numbers in scientific notation, which is useful for very large or small numbers.

Q5: Are there numbers that can't be converted?
A: Invalid inputs (like text or malformed numbers) will return an error. Some fractions have infinite decimal representations (like 1/3 = 0.333...).
