Performs a bitwise mask set operation.

A number, bitwise masked with length bits of mask beginning at start.

Mathematical functions

BitMaskSet(number, mask, start, length)

BitMaskClear, BitMaskRead

Parameter

Description

number

32-bit signed integer

mask

32-bit signed integer; mask

start

Integer, in the range 0-31, inclusive; start bit for mask

length

Integer, in the range 0-31, inclusive; length of mask

Bit functions operate on 32-bit signed integers, in the range -2147483648 - 2147483647. 

<h3>BitMaskSet Example</h3>
<p>Returns number bitwise masked with length bits of mask beginning at start.

<p>BitMaskSet(255, 255, 4, 4): 
<cfoutput>#BitMaskSet(255, 255, 4, 4)#</cfoutput>
<p>BitMaskSet(255, 0, 4, 4): 
<cfoutput>#BitMaskSet(255, 0, 4, 4)#</cfoutput>
<p>BitMaskSet(0, 15, 4, 4): 
<cfoutput>#BitMaskSet(0, 15, 4, 4)#</cfoutput>
