Public Member Functions | |
| Numeric () noexcept | |
| Default constructor. | |
| Numeric (short value) | |
| Creates a numeric value from an integer. | |
| Numeric (unsigned short value) | |
| Creates a numeric value from an integer. | |
| Numeric (int value) | |
| Creates a numeric value from an integer. | |
| Numeric (unsigned value) | |
| Creates a numeric value from an integer. | |
| Numeric (long value) | |
| Creates a numeric value from an integer. | |
| Numeric (unsigned long value) | |
| Creates a numeric value from an integer. | |
| Numeric (long long value) | |
| Creates a numeric value from an integer. | |
| Numeric (unsigned long long value) | |
| Creates a numeric value from an integer. | |
| Numeric (float value) | |
| Creates a numeric value from a double; may lose accuracy. | |
| Numeric (double value) | |
| Creates a numeric value from a double; may lose accuracy. | |
| Numeric (long double value) | |
| Creates a numeric value from a double; may lose accuracy. | |
| template<unsigned otherPrecision, unsigned otherScale> | |
| Numeric (hyperapi::Numeric< otherPrecision, otherScale > other) | |
| Creates a numeric value from another numeric value with different precision and scale. | |
| Numeric (hyperapi::string_view value) | |
| Creates a numeric value from a string representation. | |
| std::string | stringValue () const |
Gets an exact string representation, which is round-trip compatible with the constructor, i.e., n == Numeric(n.stringValue()) | |
| int64_t | intValue () const |
| Gets an integer representation of this value; if the value has fraction digits, these will be truncated. | |
| operator int64_t () const | |
| Explicit conversion to int64_t. | |
| double | doubleValue () const noexcept |
| Gets a double representation of this value; may lose accuracy. | |
| operator double () const noexcept | |
| Explicit conversion to double. | |
| std::string | toString () const |
| Gets a string representation for debugging. | |

| HyperException | if the value cannot be represented with the specified precision and scale. |
|
explicit |
Creates a numeric value from another numeric value with different precision and scale.
| HyperException | if the value cannot be represented with the specified precision and scale. |
|
explicit |
Creates a numeric value from a string representation.
| HyperException | if value is not a valid numeric representation or overflows. |
| int64_t hyperapi::Numeric< precision_value, scale_value >::intValue | ( | ) | const |
Gets an integer representation of this value; if the value has fraction digits, these will be truncated.
