I'm not a computer scientist. I don't know about buffers or bytes---nor do I want to.
I'm an engineer. I struggle plenty with my calculus and linear algebra and systems control. It's too much as is, frankly.
But I have a device sending an array with two values---pressure and temperature, say---into node-red through a TCP connection.
And for some mind-boggling reason, those numbers come in as buffers of bytes. I can't work with bytes. Or strings. I need numbers. The two numbers that my device communicated to node-red.
So how how how does a human get those numbers out of this TCP node that insists on providing buffers?
All my schooling was done in decimal numbers. All my math. All my programming. I know nothing about bytes and I wish wish wish I knew why node-red can't just give me numbers when I transmit numbers.
