43
// decimal_point = -2.
44
// Halfway cases are rounded towards +/-Infinity (away from 0). The call
45
// FastFixedDtoa(0.15, 2, ...) thus returns buffer = "2", decimal_point = 0.

47
// shortest representation of the input.
48

49
// This method only works for some parameters. If it can't handle the input it
50
// returns false. The output is null-terminated when the function succeeds.
