This isn’t new, but handy to have.  In order to tell the compiler which data type we’re using, we use suffix notation as follows:

  • Unsigned integer, U: e.g. 34506U

  • Long integer (signed), L: e.g. 5297532L

  • Unsigned long integer, UL: e.g. 30958UL

  • Float, F: e.g. 13.6F

  • Double, D: e.g. 14.3D

  • Decimal, M: e.g. 19.95M
