将小数转换为最简分数。
Converting a decimal back into a fraction is often necessary when you need to express a value exactly, without the rounding errors that can occur with decimals. This process is common in engineering, construction, and mathematics. Our Decimal to Fraction Converter doesn't just give you any fraction; it calculates the most simplified version by finding the greatest common divisor. Whether you have a simple terminating decimal like 0.75 or a more complex one, this tool will help you find the equivalent ratio of two whole numbers.
工作原理
The converter analyzes the number of decimal places in your input. It creates a fraction with a power of 10 as the denominator (e.g., 0.12 becomes 12/100). Then, it uses the Euclidean algorithm to find the Greatest Common Divisor (GCD) and divides both the numerator and denominator by it to provide the simplest possible fraction.
计算公式
Decimal → Part / 10^n → Simplified Fraction
计算示例
1. **Standard**: 0.5 = **1/2**.
2. **Precise**: 0.125 = **1/8**.
