Decimal to Fraction Conversion:
From: | To: |
Decimal to fraction conversion is the process of expressing a decimal number as a fraction (a ratio of two integers). This is particularly useful in mathematics, engineering, and sciences where exact fractional representations are preferred over decimal approximations.
The calculator uses the following mathematical relationship:
Where:
Explanation: The calculator implements a continued fraction algorithm to find the simplest fraction that approximates the decimal value within the specified precision.
Details: Fractional representations are often more precise than decimal approximations and are essential in many mathematical proofs, engineering specifications, and scientific calculations where exact ratios are required.
Tips: Enter the decimal value you want to convert. Select the desired precision level (low, medium, or high). Higher precision will yield more accurate fractions but may result in larger numerators and denominators.
Q1: Why would I need to convert decimals to fractions?
A: Fractions provide exact representations, while decimals are often approximations. Fractions are preferred in many mathematical and engineering contexts.
Q2: What's the difference between the precision levels?
A: Low precision (0.01) will find simpler fractions that are approximately correct. High precision (0.0001) will find more complex fractions that are more accurate.
Q3: Can all decimals be exactly represented as fractions?
A: Only terminating decimals can be exactly represented as fractions. Repeating decimals can be represented exactly using special notation, while irrational numbers cannot be exactly represented as fractions.
Q4: What's the largest number this calculator can handle?
A: The calculator can handle most practical values, but extremely large or small numbers may cause precision issues due to floating-point limitations.
Q5: How does this differ from standard calculator fraction functions?
A: This provides more control over precision and shows both the exact fraction and its components (numerator and denominator) separately.
