Yes, but implementing two new functions was easier :)

Are you OK with the following syntax?

  "%f32d"    // float32 in base 10
  "%f64d"    // float64 in base 10

  // With explicit precision
  "%f32.7d"
  "%f64.15d"

  // And other styles
  "%e32d"
  "%e64d"
  "%g32d"
  "%g64d"

In future we can also support other bases (like "%f32b" or "%f64x").
