A number in matlab by default uses how much memory?(adsbygoogle = window.adsbygoogle || []).push({});

my professor asked me this question today and I wasnt sure.

In matlab I assigned a random number to the variable x

>> x = 5.5623

and then used the "whos" command to determine how many bytes were stored. According to "whos", the number required 8 bytes of memory.

However, 8 wasnt part of the multiple choice.

the multiple choice were...

a. 64 bits

b. Depends on its length

c. 8 bits if it has no decimal, 32 bits if it has a decimal

d. 4 megabytes

could any1 shine some light on this problem for me, any advice would be much appreciated
