I want to extract the high and low parts to interpret it and convert to binary code, but such a hugh number (represented by a string) isn't easy to extract from the string directly its high and low parts.
If the string you want to parse is 64 characters, then use the String Subset function (String palette) twice. To get the first 32 characters, set offset to 0 and length to 32. To get the last 32 characters, set offset to 32 and length to 32.
LabVIEW can't handle a 64-bit integer. You will have to store it as two 32-bit integers. If you need exact math on those 64-bit intergers you will have to make up your own routines to handle the carries and what not. If you just need pretty good accuracy, covert both 32-bit integers to double, multiply the upper 32-bit number by 2*32 (also a double) and then add the lower 32-bit number to it.
