* "divisbile" → "divisible"
* "We can’t make new words" → "We can’t make up new words"

For example, suppose cell A2 has 20/06/2020 21:00. We can use Mod(A2,1) - 1 being the divisor - to get just the time 21:00, but using any number other than 1 or 2 also returns a whole number along with time value. Does anyone know how Mod works with decimals?

The modulo equation is:

a - floor ( a / b ) * b

14 - floor ( 14 / 12 ) * 12
14 - 1 * 12
14 - 12 = 2

So 14 mod 12 = 2

12 x 9 + 3 = 111
123 x 9 + 4 = 1111
1234 x 9 + 5 = 11111
12345 x 9 + 6 = 111111
123456 x 9 + 7 = 1111111
1234567 x 9 + 8 = 11111111
12345678 x 9 + 9 = 111111111
123456789 x 9 +10= 1111111111
