Questions tagged [fractions]

Fractions, or "fractional numbers" (lit. "broken numbers"), or "rational numbers", are numbers expressed as the ratio of two integers, such as 1/2 or 23/17.

In computing and programming, fractional (or "rational") numbers are an alternative to floating point numbers: Since numerator and denominator are stored as integers, the representation is exact, as opposed to most floating point implementations, which cannot represent most rational numbers exactly. Arbitrary-precision ("bignum") libraries usually contain support for rational numbers.

Finding the closest integer fraction to a given random real between 0..1, given ranges of numerator and denominator

Given two ranges of positive integers x: [1 ... n] and y: [1 ... m] and random real R from 0 to 1, I need to find the pair of elements (i,j) from x and y such that x_i / y_j is closest to R. What is the most efficient way to find this pair?
