R help - Nov 2012 - Problem with

Hi, can someone tell me what is wrong in this function:

ilecyfr=function(x){
if (x=0){ 
return(1)
} else {
k=0
while (abs(x)/10^k >0) {
k=k+1
} return(k)
}}

So if x == 0 (that's your first error and possibly a fatal one, but
let's then leave it behind) and you then want the function to return 0.
Otherwise you want to test whether abs(x)/10^0 is greater than 0 and then keep
increasing k until .... abs(x)/10^k is no longer >0 and then return k?
