Help me why function not return exactly value

[thanhhavdt]

function: send_data_DKX(); return exactly value with read_Data_DKX_song_met(), but not with read_Data_DKX_song_deximet()?
example: when Data_DKX = 10000 (a=10; b=0;c=0;d=0) is true, but Data_DKX = 10001 (a=10; b=0;c=0;d=1) not true
Please help me

Your comment and function do not match.

It'd be easier to see your error if you break down the equation !
ie
answer=first math term 'a'
answer =answer + 2nd math term 'b'
answer =answer + 3rd math term 'c'
answer=answer + 4th math term 'd'

Having it in one long line of code can be very confusing and hard to read.
Now once you have the correct code, you could reduce to one line.

Also put comments at the end of lines of code. Old habit from assembler days but it really,really helps and cost you nothing. Handy for when you ask 'is this right ?' or 3 days later when you ask yourself WHY did I code this mess ??

In read_Data_DKX_song_met(), Data_DKX= 10000; 10002; ....13400
but in read_Data_DKX_song_deximet(), Data_DKX= 10001; 10002; ....13999
function read_Data_DKX_song_deximet() return exactly value with even number (Data_DKX= 10000; 10002; ....) but not with odd number (Data_DKX= 10001; 10003; ....). Please heplme
