Enum type for float rounding style
Enumerated type with possible rounding styles for floating types. It is the type of member round_style in the numeric_limits class template.
It is defined as:
1
2
3
4
5
6
7
|
enum float_round_style {
round_indeterminate = -1,
round_toward_zero = 0,
round_to_nearest = 1,
round_toward_infinity = 2,
round_toward_neg_infinity = 3
};
|
With the following possible values:
| label | value | meaning |
|---|
| round_intermediate | -1 | Rounding style cannot be determined at compile time |
| round_toward_zero | 0 | Rounding style toward zero |
| round_to_nearest | 1 | Rounding style to the nearest representable value |
| round_toward_infinity | 2 | Rounding style toward infinity |
| round_toward_neg_infinity | 3 | Rounding style toward negative infinity |
The default value in the non-specialized numeric_limits class for its round_style member is round_toward_zero (0).
