MATH(CRCn data [,length] [,polynome] [,startmask] [,endmask] [,reverseIn] [,reverseOut]
Calculates the CRC to n bits (8, 12, 16, 32) of "data". "data" can be an integer or floating point array or a string variable. "Length" is optional and if not specified the size of the array or string length is used. The defaults for
startmask, endmask reverseIn, and reversOut are all zero. reverseIn, and reversOut are both Booleans and take the value 1 or 0. The defaults for polynomes are CRC8=&H07, CRC12=&H80D, CRC16=&H1021, crc32=&H04C11DB7 eg, for crc16_CCITT use MATH(CRC16 array(), n,, &HFFFF)
