| <li>any: ok for all types</li> |
| <li>boolean: byte, short, long, hyper, float, double, (any *3), boolean, char, (string *12). 0 => false, != 0 => true</li> |
| <li>char: byte, short, (long *1), (hyper *1), (float *7), (double *7), enum, (any *3), boolean, char, (string *13)</li> |
| <li>string: byte, short, long, hyper, float, double, enum, (any *3), boolean, char, string</li> |
| <li>struct: (any *3), (struct *14)</li> |

| rules: |
| <ul> |
| <li>1: only converts if the value is in the range of the target type.</li> |
| <li>2: only converts if the value, not the position, of the enum is in the range of the target type.</li> |
| <li>3: get value until it is not an any. Then convert it with the other rules.</li> |
| <li>4: only converts if the value of the character is between 0 - 255.</li> |
| <li>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.</li> |
| <li>7: only converts if the value is in the range of the target type. |
| The value is rounded to an integer.</li> |
| <li>8: only converts if the float can be converted back to the same enum value.</li> |
| <li>9: only converts if the number is one of the enumeration type values. Normally you need |
| reflection information of the enum type.</li> |
| <li>10: only converts if it is the same enumeration type.</li> |
| <li>11: only converts if the string contains the name of an enumeration type value. Normally you need |
| core reflection information of the enum type.</li> |
| <li>12: only converts if the value of the string is "1", "true" or "0", "false". The comparison |
| is case insensitive.</li> |
| <li>13: only converts if the length of the string is 1 or 0.</li> |
| <li>14: only converts if the types are equal or the source type is derived from the destination |
| type.</li> |
| <li>15: only converts if each element of the source sequence can be converted to an element |
| of the destination sequence.</li> |
