Detailed Description
Quantizer to apply scale/offset values.
Retains scales for both directions to avoid floating-point division for maximum efficiency.
Constructor & Destructor Documentation
| QUANTIZER_VALUES::QUANTIZER_VALUES | ( | ) | [inline] |
Default constructor, uses scale of 1 and offset of 0.
| QUANTIZER_VALUES::QUANTIZER_VALUES | ( | double | ScaleQtoD, | |
| double | OffsetQtoD | |||
| ) | [inline] |
Construct with scale and offset.
- Parameters:
-
ScaleQtoD Scale from "quantized" to "dequantized" must not be 0 OffsetQtoD Offset from "quantized" to "dequantized", applied after scaling
Member Function Documentation
| double QUANTIZER_VALUES::CalcDouble | ( | double | ValueQ | ) | const [inline] |
Calculate "dequantized" value from quantized value, applying scale and offset.
- Parameters:
-
ValueQ Quantized (integer) value
| INT16 QUANTIZER_VALUES::CalcPrecision | ( | ) | const [inline] |
Calculate precision (number of decimal places) based on scale.
| double QUANTIZER_VALUES::CalcRaw | ( | double | ValueD | ) | const [inline] |
Calculate "raw" value with quantization scale/offset removed, with no rounding.
- Parameters:
-
ValueD Dequantized value
| double QUANTIZER_VALUES::GetOffset | ( | ) | const [inline] |
Get offset from "quantized" to "dequantized", applied after scaling.
| double QUANTIZER_VALUES::GetScale | ( | ) | const [inline] |
Get scale from "quantized" to "dequantized".
| void QUANTIZER_VALUES::Set | ( | double | ScaleQtoD, | |
| double | OffsetQtoD | |||
| ) | [inline] |
Set scale and offset values.
- Parameters:
-
ScaleQtoD Scale from "quantized" to "dequantized" must not be 0 OffsetQtoD Offset from "quantized" to "dequantized", applied after scaling
| void QUANTIZER_VALUES::SetOffset | ( | double | OffsetQtoD | ) | [inline] |
Set offset.
- Parameters:
-
OffsetQtoD Offset from "quantized" to "dequantized", applied after scaling
| void QUANTIZER_VALUES::SetScale | ( | double | ScaleQtoD | ) | [inline] |
Set scale from "quantized" to "dequantized".
- Parameters:
-
ScaleQtoD Scale from "quantized" to "dequantized" must not be 0
