Please can anyone tell me the command syntax to convert binary to decimal representation using the BS2 board.

There are several different ways to do what you want. The place to look for a detailed explanation and examples is in the BASIC Stamp Syntax and Reference Manual or in the help files of the Stamp Editor.

There's an operator DIG used to provide a decimal digit of the decimal representation of a number.

There's what's called the DEC formatter used in a variety of I/O statements including SERIN, SEROUT, DEBUG, and DEBUGIN among others. The various formatters are also discussed in one of the appendices of the Manual..

Constants when coding? Outputting with a serial command? Doing something else? We need more information on what you intend to do.

edit: Mike! You did it again!...

For example : My result3 in Line1: is in Binary representation, and I am trying to do a conversion to mill volts using Line 2 statement. My result in Line2 is not correct because I am mixing Binary and decimal value all together. So I would like to convert my Binary result to Decimal before proceeding with Line 2.
Verification: I kept a Debug command after Line1 and Line2 and it gave me different answers. such as
result3= 3918( This is correct)
mVolts3= 0006(This is not correct)

CODE: .......
Line 1: result3 = result3 & value3
Line 2: mVolts3 = ((result3 *5000)/4095 )

You have to try harder than that. Give us something to work with: attach the full source code, with comments on each line where you think it should be decimal or binary and include what you are trying to do.

If result3=3918, then you will have to use different math to convert to millivolts. The formula, 3918 * 5000, overflows the 16 bit limit. Are the values 5000 and 4095 constants? It looks like conversion of a 12 bit ADC reading with a 5 V reference. If so, try one of the following formulae:

mVolts3 = result3 */ 313


mVolts3 = result3 ** 14484 + result3 ' more accurate

See */ and ** operators in the PBASIC reference materials.
