Functions |
| int | wxFinite (double x) |
| | Returns a non-zero value if x is neither infinite nor NaN (not a number), returns 0 otherwise.
|
| bool | wxIsNaN (double x) |
| | Returns a non-zero value if x is NaN (not a number), returns 0 otherwise.
|
| wxFloat64 | wxConvertFromIeeeExtended (const wxInt8 *bytes) |
| | Converts the given array of 10 bytes (corresponding to 80 bits) to a float number according to the IEEE floating point standard format (aka IEEE standard 754).
|
| void | wxConvertToIeeeExtended (wxFloat64 num, wxInt8 *bytes) |
| | Converts the given floating number num in a sequence of 10 bytes which are stored in the given array bytes (which must be large enough) according to the IEEE floating point standard format (aka IEEE standard 754).
|
| int | wxRound (double x) |
| | Small wrapper around round().
|
| bool | wxIsSameDouble (double x, double y) |
| | Returns true if both double values are identical.
|
| bool | wxIsNullDouble (double x) |
| | Return true of x is exactly zero.
