// getIntApprox converts the digits in slice digits[start:end] to an integer
// according to the following rules:
//   - Let i be asInt(digits[start:end]), where out-of-range digits are assumed
//     to be zero.
//   - Result n is big if i / 10^nMod > 1.
//   - Otherwise the result is i % 10^nMod.
//
// For example, if digits is {1, 2, 3} and start:end is 0:5, then the result
// for various values of nMod is:
//   - when nMod == 2, n == big
//   - when nMod == 3, n == big
//   - when nMod == 4, n == big
//   - when nMod == 5, n == 12300
//   - when nMod == 6, n == 12300
//   - when nMod == 7, n == 12300

// MatchDigits computes the plural form for the given language and the given
// decimal floating point digits. The digits are stored in big-endian order and
// are of value byte(0) - byte(9). The floating point position is indicated by
// exp and the number of visible decimals is scale. All leading and trailing
// zeros may be omitted from digits.

// The following table contains examples of possible arguments to represent
// the given numbers.
