Question

Answer 1

The number with the least magnitude is zero.

The smallest positive integer is 1.  The smallest positive real number does not exist.  The most negative integer, and the most negative real number, do not exist.

The most negative number that can be represented in an n-bit signed integer register is -2^(n-1); for 8 bits, this is -128, for 16 bits, this is -32768, etc..

Answer 2

Answer:

"Least" is the superlative of "less," which cannot be used to describe "number." It kind of depends on the rest of the sentence. 'Fewest' is a superlative. You don't need to add the word 'number'.
