Stylecop - Determine if Double or Float

I'm using Stylecop to come up with some custom rules and I'm trying to determine if I have a double or a float.

I'm able to walk through the statement and get a CSTokenType. The CSTokenType is number and can be read as a string. But since it's just a Number I have no real way of knowing if it's an int, float , long , double or whatever.

Any ides on h开发者_Python百科ow I can check to see what the primitive type is?

EDIT

To decide whether a number literal is a double or float, you have to check if and if yes, which suffix is present in CsToken.Text (when CsTokenType == CsTokenType.Number).

Some examples:

• 15 is an integer
• 0.15 is a double
• 0.15d is a double
• 0.15f is a float
• 0.15m is a decimal
