Digital Binary Converter

Support float and binary / hexadecimal conversion, double and binary / hexadecimal conversion, short and binary / hexadecimal conversion, int and binary / hexadecimal conversion, long and binary / hexadecimal conversion. The byte order needs to be selected during conversion, and the default is large end order. Big end mode means that the high byte of data is saved in the low address of memory. Small end mode means that the high byte of data is saved in the high address of memory.

CRC Calculation Online

The cyclic redundancy check calculation function of CRC8, CRC16, CRC32 and crc64 is provided to detect or verify possible errors after data transmission or saving. It uses the principle of division and remainder to detect errors. When calculating, pay attention to different algorithms (including polynomial, initial value, whether to reverse, etc.), and the calculation results will be different.
