## Detailed Description

Compression oracle based on absolute difference.

## Constructor & Destructor Documentation

## ◆ AbsDiff() [1/2]

AbsDiff | ( | float | tolerance = `-1.0f` | ) |
| inline

Note
  The default value of -1 means it's un-initialized!

## ◆ AbsDiff() [2/2]

AbsDiff | ( | const AbsDiff & |  | ) |
| default

## Member Function Documentation

## ◆ getTolerance()

float getTolerance | ( |  | ) | const
| inline

## ◆ operator()()

bool operator() | ( | float | exact,
|  | float | approx
| ) |  | const
| inline

Return true if the approximate value is within the accepted absolute error bounds of the exact value.
