Hi, is there a function that extract the upper half of an integer (most significants bits) and the lower half? Thanks

Answer 1

[per isakson]

See: bitget

C = bitget(A, bit) returns the value of the bit at position bit in A.

Answer 2

[Walter Roberson]

For anything other than 8 bit integers, typecast() the integer into the unsigned integer type which is half of the size. You may have to deal with byte order problems, though.
