As far as I know, %g will select %f or %e automatically, which is good for formatting.
The compiler would convert the float to double, then printf will output the double (8 bytes) value.
I am not quite sure on this. So I don't think this will bring in any issue. What kind of problem do you meet?

I agree with output the hex value at first glance of the patch, but the output asm would looks like
a little messy, so I don't think it is a good idea to output the hex value.
    (    1308)  mul(16)         g110<1>:F       g112<8,8,1>:F   1e-30F (0xda24260) { align1 WE_normal 1H };

Thanks!
