Remove the decimal

Hello,

I have a number received from nodered MQTT and looks like this 228.90v and i need to change it in 228v.
I use MultiBinding with {0:N0} string format for decimal. In Designer window i have listed the value like 229v, but when i load the file into android phone app i receive the value like this 2.289v. I belive {0:N0} round the number, is it possible just to remove the decimal but not rounding the number ?
Can you help me with some info ?
Thank you.
