excel vba - Use of symbol # (hash) in VBA Macro -


what meaning of use of # symbol in excel vba?

it used this:

 = b /100#

i don't understand significance of # after 100?

the type-declaration character double number sign (#). called hash

other type declaration characters are:

  1. integer %
  2. long &
  3. currency @
  4. single !
  5. double #
  6. string $

don't understand significance of # here.

it implies when expression evaluated, number in front of type declaration character treated specific data type instead of variant.

see example, same.

sub sample1()     dim a#      = 1.2      debug.print end sub  sub sample2()     dim double      = 1.2      debug.print end sub

edit

let me explain little more in detail.

consider 2 procedures

sub sample1()     dim double, b integer      b = 32767     = b * 100      debug.print end sub  sub sample2()     dim double, b integer      b = 32767     = b * 100#      debug.print end sub

question: 1 of them fail. can guess one?

ans: 1st procedure sub sample1() fail.

reason:

in sample2, when b * 100# result of calculation of type double. since within limits of double, calculation succeeds , result assigned variable a.

now in sample1, when b * 100 result of calculation of type integer, since both operands of type integer. result of calculation exceeds limits of integer storage. result error out.

hope helps :)
