This is a special numeric value representing any value greater than Number.MAX_VALUE. magnitude - big-endian binary representation of the magnitude of the number. Example In the computer world, we need a memory location where we can store the values for these sets, and this location must be finite as the memory of a computer is finite. Both are 64 bits long, but double has to use some bits for the exponent, leaving fewer bits to represent the magnitude. If we multiply negative infinity with NaN, we will get NaN as a result.
