Save bytes in float variable

[rob97i]

@PieterP

You cannot do this, the %X format specifier expects an unsigned int, not a float (which is promoted to double when passed to a variadic function).
The compiler should have warned you about that:

Thanks that was the problem:
with : printf("; lat_dist: %.2f ; ", Lat_delta_distance);
instead of the %X format worked for me, but my compiler didn´t noticed me for that.
so Thank you!.
