pine script – Issue with float lower than 1

I’ve got a very strange issue on pine script v4. My variables lower than 1 are considered like 0 🙁

For exemple :

myConst = 14
myVariable = 2 / (myConst + 1) //the result is 0.1333333
plot(100 / myVariable)

This code return me an error at the last line : “Division by zero”

I tried that too, but with no effects

float myVariable = 2 / (myConst + 1)

Thanks for your help…
