Base-class for quantized float leaf nodes.

## Member Typedef Documentation

## ◆ FloatType

using FloatType = float

## ◆ ValueType

using ValueType = float

## Member Function Documentation

## ◆ getAvg()

float getAvg | ( |  | ) | const
| inline

return the quantized average of the active values in this node

## ◆ getDev()

float getDev | ( |  | ) | const
| inline

return the quantized standard deviation of the active values in this node

Note
  0 <= StdDev <= max-min or 0 <= StdDev/(max-min) <= 1

## ◆ getMax()

float getMax | ( |  | ) | const
| inline

return the quantized maximum of the active values in this node

## ◆ getMin()

float getMin | ( |  | ) | const
| inline

return the quantized minimum of the active values in this node

## ◆ init()

void init | ( | float | min,
|  | float | max,
|  | uint8_t | bitWidth
| ) |  |
| inline

## ◆ memUsage()

static uint64_t memUsage | ( |  | ) |
| inlinestatic

## ◆ padding()

static constexpr uint32_t padding | ( |  | ) |
| inlinestaticconstexpr

Return padding of this class in bytes, due to aliasing and 32B alignment.

Note
  The extra bytes are not necessarily at the end, but can come from aliasing of individual data members.

## ◆ setAvg()

void setAvg | ( | float | avg | ) |
| inline

Note
  min <= avg <= max or 0 <= (avg-min)/(min-max) <= 1

## ◆ setDev()

void setDev | ( | float | dev | ) |
| inline

Note
  0 <= StdDev <= max-min or 0 <= StdDev/(max-min) <= 1

## ◆ setMax()

void setMax | ( | float | max | ) |
| inline

Note
  min <= X <= max or 0 <= (X-min)/(min-max) <= 1

## ◆ setMin()

void setMin | ( | float | min | ) |
| inline

Note
  min <= X <= max or 0 <= (X-min)/(min-max) <= 1

## ◆ setOrigin()

void setOrigin | ( | const T & | ijk | ) |
| inline
