| Component | Version | macOS | Windows | Linux | Server | iOS SDK |
| Math | 4.1 | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes |
Parameters
| Parameter | Description | Example |
|---|---|---|
| value1 | The first number. | 5 |
| value2... | The second number. | 6 |
Result
Returns number.
Description
Perform bitwise AND operation.Only for integer numbers. You can pass several values to combine more than 2 values.
Updated to use 64-bit signed integers in version 7.3.
This function takes variable number of parameters. Pass as much parameters as needed separated by the semicolon in FileMaker.
Please repeat value2 parameter as often as you need.
Examples
Applies bitwise and for three numbers which gives 16:
MBS("Math.BitwiseAND"; 255; 48; 18)
Split MIDI Timestamp:
# last five bits are frame counter
Set Variable [$Frame; MBS("Math.BitwiseAND"; TimeStamp; 31)]
# Seconds are in 2nd byte, so take 6 bits after shifting 8 to right
Set Variable [$Second; MBS( "Math.BitwiseAND"; MBS( "Math.BitwiseShiftRight"; TimeStamp; 8 ); 63)
# Minutes are in 3rd byte, so take 6 bits after shifting 16 to right
Set Variable [$Minute; MBS( "Math.BitwiseAND"; MBS( "Math.BitwiseShiftRight"; TimeStamp; 16 ); 63)
# Hours are in 4th byte: take 5 bits after shifting 24 to right
Set Variable [$Hour; MBS( "Math.BitwiseAND"; MBS( "Math.BitwiseShiftRight"; TimeStamp; 24 ); 31)
