# MATLAB: Couldn’t figure out what’s not working

hi, this is the code
executing => THIS IS THE FIRST ITERATION
tab =
     7     8     9    10    11    12    13    14    15    16    17    21    22    25
f1 =
236
m1 =
   12
r1 =
    0
wi =
    0
f =
240
but the real result is
f1 =
   236
m1 =
    11
r1 =
    16
wi =
     1
f =
   232
'f' should be 232 not 240 and it is the same code, where is this 240 coming from??
thank you

• the problem is that your f1 is not a double but an integer hence the division also gives an integer
if you cast f1 to be a double you should get the expected result
f1 = double(f1);m1 = floor(f1/delta)etcetera
