Bit Clear (Fixed-Point Blockset)

Set the specified bit of the stored integer to zero

Library

Bits

Description

The Bit Clear block is a masked block that sets the specified bit, given by its index, of the stored integer to zero. Scaling is ignored.

You can specify the bit to be set to zero with the Index of bit parameter, where bit zero is the least significant bit.

True floating-point data types are not supported.

Parameters and Dialog Box

Index of bit: Index of bit where bit 0 is the least significant bit.

Examples

If the Bit Clear block is turned on for bit 2, bit 2 is set to 0. A vector of constants
2.^[0 1 2 3 4] is represented in binary as [00001 00010 00100 01000 10000]. With bit 2 set to 0, the result is [00001 00010 00000 01000 10000], which is represented in decimal as [1 2 0 8 16].
