Float to string with fixed precision
In Javascript, I am able to do:
const value = 0.8999999999
const roundedValueAsString = value.toFixed(2)
console.log(roundedValueAsString) // "0.90"
console.log(typeof roundedValueAsString) // "string"
There is similar behaviour in Elixir
Hello! Good idea, thank you. It would go in the float module and we'd need to determine a name.
@lpil I am currently working on this. How do we feel about to_fixed_string or to_string_fixed for the function name?
Since round
, truncate
, and to_string
already exist, I think to_fixed_string
sounds like a good name. Anyone else have ideas?
