This service provides a widening converter converting from one type to another, if possible. 
What is possible? 
- 
byte: byte, (short *1), (long *1), (hyper *1), (float *1), (double *1), (enum *2), (any *3), boolean, (char *4), (string *5) 
- 
short: byte, short, (long *1), (hyper *1), (float *7), (double *7), (enum *2), (any *3), boolean, char, (string *5) 
- 
long: byte, short, long, (hyper *1), (float *7), (double *7), enum, (any *3), boolean, char, (string *5) 
- 
hyper: byte, short, long, hyper, (float *7), (double *7), enum, (any *3), boolean, char, (string *5) 
- 
float: byte, short, long, hyper, float, (double *7), (enum *8), (any *3), boolean, char, (string *5) 
- 
double: byte, short, long, hyper, float, double, enum, (any *3), boolean, char, (string *5) 
- 
enum: (byte *9), (short *9), (long *9), (hyper *9), (float *9), (double *9), (enum *10), (any *3), (string *11) 
- 
void: ok for all types 
- 
any: ok for all types 
- 
boolean: byte, short, long, hyper, float, double, (any *3), boolean, char, (string *12). 0 => false, != 0 => true 
- 
char: byte, short, (long *1), (hyper *1), (float *7), (double *7), enum, (any *3), boolean, char, (string *13) 
- 
string: byte, short, long, hyper, float, double, enum, (any *3), boolean, char, string 
- 
struct: (any *3), (struct *14) 
- 
interface: (any *3), (struct *14) 
- 
exception: (any *3), (exception *14) 
- 
union: (any *3), (union *14) 
- 
sequence: (any *3), (sequence *15) 
rules: 
- 
1: only converts if the value is in the range of the target type. 
- 
2: only converts if the value, not the position, of the enum is in the range of the target type. 
- 
3: get value until it is not an any. Then convert it with the other rules. 
- 
4: only converts if the value of the character is between 0 - 255. 
- 
5: only converts if the value represents a decimal, hexadecimal (0x...) or a floating point number. Examples: 10, 0x10, 10.045, 10,555, +10, +10.6e10, -10.6e-10, .16. 
- 
7: only converts if the value is in the range of the target type. The value is rounded to an integer. 
- 
8: only converts if the float can be converted back to the same enum value. 
- 
9: only converts if the number is one of the enumeration type values. Normally you need reflection information of the enum type. 
- 
10: only converts if it is the same enumeration type. 
- 
11: only converts if the string contains the name of an enumeration type value. Normally you need core reflection information of the enum type. 
- 
12: only converts if the value of the string is "1", "true" or "0", "false". The comparison is case insensitive. 
- 
13: only converts if the length of the string is 1 or 0. 
- 
14: only converts if the types are equal or the source type is derived from the destination type. 
- 
15: only converts if each element of the source sequence can be converted to an element of the destination sequence.
