setbit(

setbit(NUMBER

, BIT

, TRUEFALSE

)
The** setbit( **function sets or clears one bit within a number, without disturbing any of the other bits.

**Parameters**

This function has three parameters:

** number** – the initial integer value.

** bit** – the bit to flip, from 1 to 64.

** truefalse** – specifies whether to set (

**Description**

This function sets or clears one bit within a number, without disturbing any of the other bits. The bit number may be from 1 to 64 and is counted backwards from the last bit. The bit will be set based on the true/false parameter - set if true, cleared if false.

`radixstr("binary",setbit(16,3,true())) ☞ `*00010100*
radixstr("binary",setbit(31,4,false())) ☞ *00010111*

Note: This function is equivalent to:

```
(thenum and onescomplement(bit(bitnum))) + (bit(bitnum) and truefalse)
```

**See Also**

- bit( -- converts a bit number (1 to 64) into a number (1, 2, 4, 8, 16, etc.)
- getbit( -- returns the value of a bit within a number.
- onescomplement( -- returns the one's complement of a 64 bit number (all bits are reversed)

10.0 | Updated | Carried over from Panorama 6.0, but now supports up to 64 bits (instead of 32). |
