floating point - Converting float to hex results in more digits than expected in C#? -

-

i'm going convert c# floating point number 2 bytes, instance have number 12.4544 , should 0x4147, or 0x41474539, i've used bitconverter.doubletoint64, gives me weird, how can 0x4147?

i'm creating modbus slave, , should send each float number 2 bytes

thanks

edit: oh dear oh dear, missed this, short answer:

use bitconverter.getbytes , pass float, shown here.

the long answer:

bitconverter doesn't support single precision floats, doubles. you'll have create c# "union", so:

[structlayout(layoutkind.explicit)] class floater {     [fieldoffset(0)]     public float thefloat;     [fieldoffset(0)]     public int theint; }

put float in thefloat , @ theint
