Can this converter handle repeating decimals like 0.666...?

Yes, the tool includes a dedicated section for repeating decimals. It uses algebraic methods to express repeating patterns as fractions, such as converting 0.333333... to 1/3, with examples showing the step-by-step equation setup.

What happens if I enter a decimal with many digits after the point?

The converter processes the digits to form a fraction with a power of 10 as the denominator, then reduces it using the greatest common divisor. Very long decimals may result in large numerator and denominator values before simplification.

Does the tool support scientific notation input?

Yes, the input field accepts decimals written in e notation (for example, 5.72e2), converting them to fractional form just like standard decimal values.

Is the resulting fraction always in lowest terms?

The tool automatically finds the greatest common divisor of the numerator and denominator and divides both by that number, ensuring the final fraction is fully reduced so the numerator and denominator share no common factors other than one.
