# bitSigToNumeric

converts a bit-significant field to a numerical value. Note that a bit field of 0x00 has no defined result.

## Declaration

```occ
virtual UInt8 bitSigToNumeric(
 UInt16binary); 
```

## Parameters

- `binary`: the bit significant field.

## Return Value

Return Value the numerical value of the highest bit set in the field.
