How can I extract high and low parts of a string that represents a 64bits decimal number?
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.
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.
