For my Project to write with a dashdoard slider to my DDC controller i need to convert the Decimal value to a IEEE-754 Floating Point.
On this site i found a correct working converter. [IEEE-754 Floating Point Converter](https://www.h-schmidt.net/FloatConverter/IEEE754.html)
is it possible to do this calculation witch a function? i attempted various functions but never get the correct Hexadecimal
can anyone help me with this one?

In what form do you want the result and what do you want to do with it?

or 42300000

i want to inject this to a DDC controller. to set a temperature with a slider. i want to merge this output into a UDP massage.

@Steve-Mcl can your buffer-parser node convert a number into a buffer containing the IEEE float value?

Hi Colin. No, only standard buffer functions (node is `Buffer` doesn't do IEEE754 AFAIK)
@rogier are you using node-red v1.3.x? If so, you could use [this IEEE754 npm module](https://www.npmjs.com/package/ieee754) in a function node.

ok thank you, i upgrade Node Red to 1.3.2 and installed the module, have you any idea how the function code must look like? can't find any examples.... ๐ฌ

Hi @rogier , i have found this ([JavaScript (Node.js) IEEE 754 Single precision Floating-Point (32-bit) binary conversion from and to both Hex and Bin ยท GitHub](https://gist.github.com/Jozo132/2c0fae763f5dc6635a6714bb741d152f)) and i put in a function node.

Hi rogier, can you share the node code that worked for you ?
Thank you!
