What’s the name of it?

double  d1 = 0d;
decimal d2 = 0L;
float   d3 = 0f;

And where can I find a reference of the characters I can use? If I want to make one cast of 0 for short, there is some letter for this?

What’s the name of it?

There’s no proper name for it, it’s usually referred to as suffix (suffix, Numeric suffix or suffix type).

And where I can find a reference of the characters I can use?

You can find a reference of the characters used by C# at that link (spine Type Suffix). Basically are:

  • M or m for decimal.
  • D or d for double.
  • F or f for float.
  • L or l for long.
  • U or u for uint.
  • UL or ul for ulong.

It is optional to write in upper or lower case, but recommended for type long use the uppercase form so as not to confuse it with the character 1 (one).

If I want to cast 0 for short, there are some lyrics for this?

No, the C# specification does not dedicate a suffix to the type shorts (nor to byte and char).

Curiosity: for the type ulong, besides UL and ul, any variation with the letters may be used L and U: Ul, uL, lu, LU, Lu, lU.
