int=0L & reads,'1100110',FORMAT='(B)',int
print,int
I don't know how int2bin works, but it could work using string itself:
bin=string(int,FORMAT='(B0)')

Hi
I may be barking completely up the wrong tree, but is this what you
want?
Arr = BYTE (BinaryString) - 48
Els = N_ELEMENTS (Arr)
Result = TOTAL (2^ LINDGEN (Els) * Arr )
all the best

Long time reader, first time poster. Greetings to all.
assuming you have a 16 character, left '0' padded string, strbin
number = total((byte(strbin) - 48b) * (2L ^ reverse(bindgen(16))))
that's what IDL does best ;) sure there's a simpler way too...
