  How can I specify higher floating-point precision when using MS_DBG()? For example:
  
  float myFloat = 0.0001875; MS_DBG(myFloat);
  
  1
  2
  
  float myFloat = 0.0001875;
  MS_DBG(myFloat);
  
  prints:
  
  0.00
  
  1
  
  0.00

  The Arduino print function defaults to two decimal places for a float. Normally, if you were using Serial.print(float) you could control the decimal places with Serial.print(float, decimalPlaces). But because of the way the MS_DBG macro is written, that won’t work. You’ll have to create a String from the number and then MS_DBG that: MS_DBG(String(float, decimalPlaces));
