CGenAddress ( CGenState state ) : void

EqualType ( ExprType t1, ExprType t2 ) : System.Boolean
FloatToArith ( Expr expr, ExprType type ) : Expr	From: float, double To: char, uchar, short, ushort, long, ulong, float, double According to MSDN "Conversions from Floating-Point Types", float cannot convert to unsigned char. I don't know why, but I follow it.
FromPointer ( Expr expr, ExprType type, Env env ) : Expr	From: pointer To: pointer, integral
IntegralPromotion ( Expr expr ) : ExprTypeKind>.Tuple	All integrals are converted to LongType or ULongType.
MakeCast ( Expr expr, ExprType type ) : Expr
MakeCast ( Expr expr, ExprType type, Env env ) : Expr
SignedIntegralToArith ( Expr expr, ExprType type ) : Expr	From: char, short, long To: char, uchar, short, ushort, long, ulong, float double
ToPointer ( Expr expr, ExprType type, Env env ) : Expr	From: pointer, integral To: pointer
TypeCast ( TypeCastType kind, Expr expr, ExprType type ) : System
UnsignedIntegralToArith ( Expr expr, ExprType type ) : Expr	From: uchar, ushort, ulong To: char, uchar, short, ushort, long, ulong, float, double Aaccording to MSDN "Conversions from Unsigned Integral Types", unsigned long converts directly to double. However, I just treat unsigned long as long.
UsualArithmeticConversion ( Expr e1, Expr e2 ) : Tuple	Perform the usual arithmetic conversion on two expressions. If either expression is DoubleType, then both are converted to DoubleType. Else, if either expression is FloatType, then both are converted to FloatType. Else, if either expression is ULongType, then both are converted to ULongType. Else, both are converted to LongType.
UsualScalarConversion ( Expr e1, Expr e2 ) : Tuple	First, convert pointers to ULongType's, then do UsualArithmeticConversion.

Perform the usual arithmetic conversion on two expressions.

If either expression is DoubleType, then both are converted to DoubleType.

Else, if either expression is FloatType, then both are converted to FloatType.

Else, if either expression is ULongType, then both are converted to ULongType.

Else, both are converted to LongType.
