Single Precision (4 byte) floats with readBin

I would like to use readBin to read a binary data
file.  Most of the data is 4-byte floating point

but,

for some reason, only double precision appears to

be

offered.  I tried 
fVariable=readBin(iFile,what=single());
and got 35.87879 which looks believable except

that

the correct value is 3.030303.  I then tried
fVariable=readBin(iFile,what=single(),4);
and got 
[1]  3.831111e+10  6.657199e+10 -5.592394e+29
-5.592397e+29

For the second call, there were two more single
precision floats of value 3.030303 followed by two
more with values 40.46 and 0.00 respectively.

Is there any way around this problem other than to
make the input data double (which I definitely do

not

want to do)? 

Many thanks in advance,
Peter.
