MOD function

Appreciate any feedback on the MOD function. I am at a loss to
understand its "mathmatics ".

From the help

Result = Number1 MOD Number2 where the result should be the remainder
of the division.

Create a quick form with 3 unbound fields where the values are all
stored as either double or long (doesnt seem to make any difference in
this case) a quick bit of code and we can play and see the results.

Ok lets try 19 Mod 6.7 in normal "maths" we end up with 2.835
(19/6.7)=2.835, we would expect to see the remainder as .8 however we
end up with .5

With 103 / 16 we would expect to see 6.437 (a remainder of .4),
however with the MOD function we get 7.

Obviously I'm missing something here,

TIA

The remainder is not the same as the decimals. In your last example
103 / 16 = 6 plus some decimals. 16 x 6 = 96. The difference between
103 and 96 is 7, which is the result of the mod function.

MOD uses integer math.
Your divisor is rounded before the MOD operation.

In your example of 19 MOD 6.7, the 6.7 is rounded to 7.
The result of 19 MOD 7 is 5.
Hence 19 MOD 6.7 = 5, since 7*2 yields 14, and the remainder is 5.

In your second example:
103 \ 16 = 6
103 MOD 16 = 7
Check:
(16 * 6) + 7 = 103

Mod is an all integer function. 16 x 6 = 96, 103 - 96 = 7.

Well, I learned something new here. I never knew you could
use the MOD function with non-integers!

OK, to answer your question. I believe you are confusing
Mod with the fractional value. In your first case:

1. 19 Mod 6.7
19 / 6.7 = 2.8358208955223 880597014925373 134. Since
the integer portion is 2
19 Mod 6.7 = 19 - (6.7 * 2) = 5.6

2. 103 Mod 16
103 / 16 = 6.4375. The integer portion is 6
103 Mod 16 = 103 - (16 * 6) = 7
