NumRolX()

Rotates bits of a numeric integer value to the left.

Syntax

NumRoL( <nMaxBits>, ;
        <nInteger>|<cHex>  , ;
        <nRotate>|<cRotate>  ) --> nInteger

Arguments

<nMaxBits>

This numeric value specifies the number of bits to use in the operation, beginning with the least significant bit (LSB). The value of <nMaxBits> must be in the range between 1 and 32.

<nInteger>

A numeric integer value is specified as second parameter.

<cHex>

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

<nRotate>

A numeric value defines how many places the bits should be rotated.

<cRotate>

Instead of a numeric value, the parameter can be a hex-encoded character string.

Return

The function returns the result of rotating <nMaxBits> bits as a numeric value.
