Enum dec::Rounding [−][src]
Algorithms for rounding decimal numbers.
The rounding modes are precisely defined in The Arithmetic Model chapter of the General Decimal Arithmetic specification.
Variants
Round towards positive infinity.
Round towards zero (truncation).
Round towards negative infinity.
Round to nearest; if equidistant, round down.
Round to nearest; if equidistant, round so that the final digit is even.
Round to nearest; if equidistant, round up.
Round away from zero.
The same as Rounding::Up
, except that rounding up only occurs
if the digit to be rounded up is 0 or 5.
After overflow the result is the same as for Rounding::Down
.
