Question

1.3=(0.5×2)+0.3
so 1.3%0.5 =0.3
but I get 1.3%0.5=0.30000000000000004
also,
3.3%1.1 =1.0999999999999996
why not 0 ?[3.3=(1.1×3)+0]

Answer 2

Nice find, @Martin

@Jed Suellas

3.3 % 1.1 = 1.0999999999999996

Use this program:

Type 3.3 and then 1.1 into the eval field.

It shows:
3.2999999999999998
1.1000000000000001

Manually:
3.2999999999999998
- 1.1000000000000001
------------------------------------------
2.1999999999999997
- 1.1000000000000001
------------------------------------------
1.0999999999999996

You can also try 3.3-1.1-1.1 for the same result.

Computer's 3.3 is less than human's 3.3
Computer's 1.1 is greater than human's 1.1
