1. Is there a way to get the highest and lowest real values? I can do high(longint) but high(real) gives me an error. Also of interest is a low(real) value (-m * 10^n) as distinct from the smallest real value (m * 10^-n)
2. For the purposes of reserving memory in block sizes that can be easily reallocated, I like to use powers of two. So if I have, e.g., a dynamic array, I might start with a size of 1024 and then double it when it hits capacity. Hopefully this smoothes memory management, as I am using a lot of memory... Anyway, what I'd like is a simple function that can quickly identify the next power-of-two larger than an arbitrary number. So if I feed the function 472, it will return 512. Thus far I haven't been able to figure out how to do this without a big if-then-else nest. Is there some clever way to request that the processor return the position of the leftmost '1' in 00101101?
