-// The result should be interpreted as buffer * 10^(point-length).
-// The buffer will be null-terminated.
-//
-// The input v must be > 0 and different from NaN, and Infinity.
-//
-// The output depends on the given mode:
-// - SHORTEST: produce the least amount of digits for which the internal
-// identity requirement is still satisfied. If the digits are printed
-// (together with the correct exponent) then reading this number will give
-// 'v' again. The buffer will choose the representation that is closest to
-// 'v'. If there are two at the same distance, than the number is round up.
-// In this mode the 'requested_digits' parameter is ignored.
-// - FIXED: produces digits necessary to print a given number with
-// 'requested_digits' digits after the decimal point. The produced digits
-// might be too short in which case the caller has to fill the gaps with '0's.
-// Example: toFixed(0.001, 5) is allowed to return buffer="1", point=-2.
-// Halfway cases are rounded up. The call toFixed(0.15, 2) thus returns
-// buffer="2", point=0.
-// Note: the length of the returned buffer has no meaning wrt the significance
-// of its digits. That is, just because it contains '0's does not mean that
-// any other digit would not satisfy the internal identity requirement.
-// - PRECISION: produces 'requested_digits' where the first digit is not '0'.
-// Even though the length of produced digits usually equals
-// 'requested_digits', the function is allowed to return fewer digits, in
-// which case the caller has to fill the missing digits with '0's.
-// Halfway cases are again rounded up.
-// 'BignumDtoa' expects the given buffer to be big enough to hold all digits
-// and a terminating null-character.
