Hello,

I have a question about type conversion in IDL.

I get a float value return by IDLffDICOM object, but it is stored in
byta[4]. Is there any way like in C as follows,

char byta[4]={103, 38, 18, 68};
float tmpv;

pf = (float *)(&bytarr);
tmpv = (float)(*pf);

convert the varible from a 4 elements byte array to a float point
variable in IDL?

Thanks a lot,
R.D.
