A strange error with WHERE [message #67485]

Dear all,
I come across a strange error with WHERE function. Could you
please help me to check it?
Here is part of the code. I will explain below the code.

outer1_begin: id_hr = where(r03_temp ge 50)
n_hr = n_elements(id_hr)

if (n_elements(id_hr) gt 1) then begin
id_max = where(r03_temp eq max(r03_temp))
lonc = lon_aoc(id_max)
latc = lat_aoc(id_max)

ii=0
outer2_begin: print,ii
ii=ii+1
lon_left = lonc-ii*0.5
lon_right = lonc+ii*0.5
lat_up = latc+ii*0.5
lat_down = latc-ii*0.5
id_box = where(lon_aoc ge lon_left)

Here lon_left=117.25, is a flot number. lon_aoc is a 80*30 matrix,
with many values larger than 117.25.
If I use id=where(lon_aoc ge 117.25), id returns right results.
However, the above code returns -1 to id_box. It is really strange.
Could anyone help me? Thank you very much!
