enum class rounding_mode {
  ceiling,
  down,
  floor,
  half_down,
  half_even,
  half_up,
  up
};

It is a rounding mode for tools::bigdecimal.

• ceiling
  • It is a rounding mode to round towards positive infinity.
• down
  • It is a rounding mode to round towards zero.
• floor
  • It is a rounding mode to round towards negative infinity.
• half_down
  • It is a rounding mode to round towards the nearest neighbor unless both neighbors are equidistant, in which case round towards zero.
• half_even
  • It is a rounding mode to round towards the nearest neighbor unless both neighbors are equidistant, in which case round towards the even neighbor.
• half_up
  • It is a rounding mode to round towards the nearest neighbor unless both neighbors are equidistant, in which case round away from zero.
• up
  • It is a rounding mode to round away from zero.
