Bug description

Calling toString on an f64 value works as expected, but doing the same on an f32 string introduces extra noise decimals. I suspect it is because the f32 value is being cast to f64 when passed into the dtoa function:

Steps to reproduce

console.log((<f64>1.1).toString());  // "1.1"
console.log((<f32>1.1).toString());  // "1.100000023841858"
