BitMaskRead

Performs a bitwise mask read operation.

Method Signature

BitMaskRead(number=[integer], start=[integer], length=[integer])

Arguments

Argument	Type	Required	Description	Default
number	integer	true	32-bit signed integer from which to read the mask.
start	integer	true	Start bit for the read mask (Integer in the range 0-31, inclusive).
length	integer	true	Length of bits in the read mask (Integer in the range 0-31, inclusive).

Examples

Bitwise Mask Read

Uses the bitMaskRead function to read each of the corresponding bits specified in the mask

Run Example

bitMaskRead( 3, 0, 1 );

Result: 1

Using non zero start parameter

Bit shift the mask 2 places

Run Example

bitMaskRead( 10, 2, 1 );

Result: 0

Using non zero read mask start and length parameters

Run Example

bitMaskRead( 10, 1, 3 );

Result: 5

Additional Examples

Run Example

writeOutput( bitMaskRead( 255, 5, 5 ) );
writeOutput( "<br>" );
writeOutput( bitMaskRead( 255, 0, 4 ) );
