How to Convert decimal(12.51) to hex value??

[Cloud05]

Hi All,

I am using LabView 8.5.

I have to convert decimal to hex value to write the data into MCU.

But my value is decimal like 12.51.

How can I convert?

Thanks,

Cloud

Hi All,

In additional information to my question,

I need to convert the decimal value 12.51 to byte[] to able to write into MCU through RS232.

How many bytes do you want to represent this value?  (4 bytes for single representation, 8 for double).?

Use the typecast function.

Hi Cloud05,

On the indicator, right click> select representation> select I16 (Word)

This will allow you to select display format in the properties dialog box.

Now press right click> select properties>Click display format> select Hexadecimal in the Types menu.

You should see small 'x' on the left of indicator indicating the value in Hexadecimal

Please see attached image.

How is the number supposed to be represented according to the manual? Some, e.g. the pump i'm working on right now, uses 1/100s as integer, i.e. 12.51 would be read/sent as 1251. Is the number supposed to be the hex representation or the text representing the hex? (Is it supposed to send 04E3 or the text '04E3')

Please check attached VI.

One array shows 8 byte representation (When 12.51 is considered as double precision)

One array shows 4 byte representation (When 12.51 is considered as single precision)

This way u can convert it to array and then transfer to serial port.

If this is what u r looking for , pls dont forget to add Kudos.
