SetValueNumber
Description
Sets the number value for a key. If the key does not exist, then
create the key and set its value. If the key already exists, then
overwrite the value of this key. If more than one key with the same name
already exists, then overwrite the value of the first key. Notice that the
IgnoreCase property (true by default) determines whether the key name will
be matched in a case-sensitive manner.
