Enum reckoner::RoundMode

pub enum RoundMode {
    Down,
    Up,
    HalfUp,
    HalfDown,
}

as a decimal value. There are four rounding modes currently supported.

Variants

Down

Truncates the value toward zero.

For example, 12.009 to 2 decimal places becomes 12.00.

Up

Rounds the value away from zero.

For example, 12.001 to 2 decimal places becomes 12.01, but 12.000 to 2 decimal places remains 12.00.

HalfUp

Rounds the value to nearest digit, half rounds upward.

For example, 12.005 to 2 decimal places becomes 12.01, but 12.004 to 2 decimal places becomes 12.00.

HalfDown

Rounds the value to nearest digit, half goes toward zero.

For example, 12.005 to 2 decimal places becomes 12.00, but 12.006 to 2 decimal places becomes 12.01.
