Why does NUM2STR not return the correct string format that I specified?

When I use NUM2STR in the following example, the result is a character array of length 6 instead of 10:
d = num2str(123.456, '%10.2f');
whos d
Name Size Bytes Class
d 1x6 12 char array
Grand total is 6 elements using 12 bytes

This is the expected behavior of NUM2STR. NUM2STR removes leading spaces from variables.
As a workaround, you can utilize the SPRINTF command, as shown in the following example:
d = sprintf('%10.2f', 123.456);
The result of the variable d will now be a character array whose length is 10 elements.
