函数说明

decode() [1/2]

template<typename ReturnT , typename ExtentT , typename ValueT >

ReturnT vlink::Quantize::decode ( ExtentT  extent, ValueT  value  )

inlinenoexcept

Dequantizes a signed integral value from [-extent,+extent].

Equivalent to decode<ReturnT>(-extent, extent, value), but avoids the generic min/max mapping setup for symmetric extent ranges.

参数

extent	Positive symmetric extent.
value	Quantized value.

返回

Dequantized value, or 0 for invalid extent.

decode() [2/2]

template<typename ReturnT , typename MinT , typename MaxT , typename ValueT >

ReturnT vlink::Quantize::decode ( MinT  quant_min, MaxT  quant_max, ValueT  value  )

inlinenoexcept

Dequantizes an integral value into a real range.

参数

quant_min	Minimum value of the real range.
quant_max	Maximum value of the real range.
value	Quantized value.

返回

Dequantized value.

encode() [1/2]

template<typename QuantT , typename ExtentT , typename ValueT >

QuantT vlink::Quantize::encode ( ExtentT  extent, ValueT  value  )

inlinenoexcept

Quantizes a value from [-extent,+extent] into a signed integral type.

Equivalent to encode<QuantT>(-extent, extent, value), but avoids the generic min/max mapping setup for symmetric extent ranges.

参数

extent	Positive symmetric extent.
value	Value to quantize.

返回

Quantized value, or 0 for invalid extent / NaN input.

encode() [2/2]

template<typename QuantT , typename MinT , typename MaxT , typename ValueT >

QuantT vlink::Quantize::encode ( MinT  quant_min, MaxT  quant_max, ValueT  value  )

inlinenoexcept

Quantizes a value from a real range into an integral type.

Details

参数

quant_min	Minimum value of the real range.
quant_max	Maximum value of the real range.
value	Value to quantize.

返回

Quantized value.
