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.

This example modifies the value of the dept_id key in the JSON string, from 100 to 999.99.
// Integer SetValueNumber ( string Key, double Value )
Double ldb_DeptID
JsonPackage ljp_Dept
ljp_Dept = Create JsonPackage
// Loads the JSON string to the JSONPackage object
ljp_Dept.loadstring ( '{"dept_id":100, "dept_name":"R & D8", "dept_head_id":105}')
ljp_Dept.SetValueNumber("dept_id", 999.99) // Sets the value of dept_id to 999.99
ldb_DeptID = ljp_Dept.GetValueNumber("dept_id") // Checks if the value is 999.99
If ldb_DeptID <> 999.99 Then
// Prints the error message if SetValueNumber failed
End If
