I use remainder inside my code with kotlin in android project but with this value I don't get the correct answer.

variable is :

```
 val vv = 1529.71
 val ratio = 0.01
 val remainder = vv.rem(ratio)

```

it's must be **zero** but **remainder** value is :
`4.5363018896793506E-15`

I don't understand why this happened.
