to 2:0.325656......x100=32.5656 ... ①0.325656......x10000=3256.56 ... IiUse ②-① to get:0.325656......x9900=3256.5656 ... -32.5656 ...0.325656......x9900=3256-32So, 0.325656......=3224/9900Induction: The fractional part of a mixed repeating decimal can be converted into fractions, the numerator of which is the difference between the number of fractional parts of the second cycle section and the number of non-cyclic parts in the fractional part. The fi

Converts an infinitely repeating decimal point to a fraction. Example: 32. 5632323232 ......... 1. Set x = 32. 5632323232 ......... Then y = x * 10000 Y = 325632. 32323232 ..... 2. z = x * 100 Z = 3256. 3232323232 ....... 3. Y-z = 322376 // note that the decimal part here is offset Y-z = x-100x That is, 9900x = 322376 X = 322376/9900 Then the simplest

[LeetCode] Fraction to Recurring Decimal Given two integers representing the numerator and denominator of a fraction, return the fraction in string format. If the fractional part is repeating, enclose the repeating part in parentheses. For example, Given numerator = 1, denominator = 2, return "0.5 ". Given numerator

Given integers representing the numerator and denominator of a fraction, return the fraction in string format.If the fractional part was repeating, enclose the repeating part in parentheses.For example,Given numerator = 1, denominator = 2, return "0.5".Given numerator = 2, denominator = 1, return "2".Given numerator = 2, denominator = 3, return "0.
