Hi Guys, I am trying to pass UFix64 args ex: ` fcl.arg(parseFloat(price), t.UFix64),` Then I get the following message : > @onflow/types Deprecation Notice========================Passing in Numbers as values for Fix64 and UFix64 types is deprecated and will cease to work in future releases of @onflow/types.Find out more here: [https://github.com/onflow/flow-js-sdk/blob/master/packages/types/WARNINGS.md#0001-[U]Fix64-as-Number=======================](https://github.com/onflow/flow-js-sdk/blob/master/packages/types/WARNINGS.md#0001-%5BU%5DFix64-as-Number=======================) However, even though using String as recommended in the git WARNINGS.md, or t.Ufix256 as introduced in the newly published FCL docs : `UFix64` `fcl.arg("64.123", t.UFix256)` nothing works … Any Help ? Thanks a lot! ---

I just found by my owned `fcl.arg(price.toString(), t.UFix64),` Thought t.String has to be used, but it was the javascript variable that has to be turned toString(), not the argument type 😘
