I use MCU to send some data to PC.For example,I want send a decimal number ''100'',I send it with HEX format "63".And I want the number I received is 100(DEC) or 63(HEX).

I think the string received in PC actually is "d"(the ASCII of d is 100),and the value displayed in the chart is 13 .

I know there are somewhere wrong,but I don't know where ,and how to convert it to the number 100.

Hi fei,

100d = 64h (char 'd' is correct)

Do you send the value 100 by just one byte containing this value (64h)? Then you have to convert your string to array of u8. If the number format is different to u8 you have to implement the proper conversion (as shown: typecast, math routine, and much more).
