// ToIntegral returns the value of a rounded to an integral value.
//
// The representation of a number is:
//
// (-1)^sign coefficient * 10^exponent
// where coefficient is an integer storing 34 digits.
//
// - If exponent < 0, the least significant digits are discarded, so that new exponent becomes 0.
// Internally, it calls Quantize(a, 1E0) with specified rounding.
// - If exponent >= 0, the number remains unchanged.

// E.g. 12.345678e2 is 12345678E-4 --> 1235E0
// 123e5 is 123E5 remains 123E5
