NumMirr()

Mirrors 8 or 16 bits of a 16-bit integer.

Syntax

NumMirr( <nInteger>|<cHex>, ;
        [<lEightBits>]      ) --> nInteger

Arguments

<nInteger>

A numeric 16-bit integer value in the range between 0 and 65535 can be specified as first parameter.

<cHex>

Alternatively, the integer can be passed as a hex-encoded character string (see NumToHex()).

<lEightBits>

If .T. (true) is passed for <lEightBits>, only the low 8 bits of <nInteger> are mirrored. The default value is .F. (false), i.e. all 16 bits are mirrored.

Return

The function returns a numeric integer value with 16 or 8 bits set in reversed order.
