This example produces the following results:

Test the sign of the following types of values:
Byte   :   0 is equal to zero.
Int16  :  -2 is less than zero.
Int32  :  -3 is less than zero.
Int64  :  -4 is less than zero.
Single :   0 is equal to zero.
Double :   6 is greater than zero.
Decimal:  -7 is less than zero.

The following type is not CLS-compliant.
SByte  : -101 is less than zero.
