Hi!
I got a decimal number, 28.1**4** .
I want to mane a method that returns the last decimal digit, in this case, **4**!
how can I do so?

Multiply by 100 and take the modulus 10?

Oh, this is SO embarrassing! I should have known that! Thanks! :)

be aware that float math can always give rounding errors, so 100 x 28.14 might become 2813(.9999)

You can round it to the nearest integer by adding 0.5 to the float value before the conversion to an integer.
