I'm finding a strange behaviour with floats in Kotlin 1.5 multiplatform
 `1F - 0.9F == 0.100000024F`
anyone know why the precision is getting messed up. I would expect `1F - 0.9F == 0.1F`

you’re better off doing FP comparisons using abs(target, current) &lt; EPS

EPS can be a small value like 1e-9

i had assumed it was a kotlin bug, looks like it's inherent to floats though huh?

If you're on the JVM use BigDecimal if you need precise arithmetic.

&gt;  it’s inherent to floats though
Or more precisly it’s a behaviour of floats according to IEEE 754 standard
