Woot! My RPN Calculator really helped me with this problem.
The answer is somewhat long, so I'm putting it in secret tags.

×For 4/9 I used ".4444"
0 = 4+4-4-4
1 = 4/4*4/4
2 = 4*4/(4+4)
3 = (4-√4)+4/4
4 = (4-√4)+(4-√4)
5 = √4+√4+(4/4)
6 = 4-4+4+√4
7 = 44/4-4
8 = 4*4-4-4
9 = 4/4+4+4
10 = 4*4-4-√4
11 = 44/(√4+√4)
12 = 4*4-√4-√4
13 = 4!-44/4
14 = 4*4-(4-√4)
15 = 44/4+4
16 = 4+4+4+4
17 = 4*4+4/4
18 = 4*4+4-√4
19 = 4!-4-4/4
20 = 4!+4-4-4
21 = 4!-(4-4/4)
22 = 4!-((4+4)/4)
23 <> 4!-(√4+4/4) --> 23 = 4!-(√4-4/4)
24 = 4!+4-√4-√4
25 <> 4!+(√4+4/4) --> 25 = 4!+√4-4/4
26 = 4!+((4+4)/4)
27 = 4!+(4-4/4)
28 = 4!+4+4-4
29 = 4!+4+4/4
30 = 4!+4+4-√4
31 <> 4!+√4/4+√4 --> 31 = 4!+√4/0.4+√4
32 = 4!+4+√4+√4
33 = 4!+4+√4/0.4
34 = (4+4)*4+√4
35 = 4!+√4+4/.4444
36 = (4+4)*4+4
37 = 4!+4+4/.4444
38 = 44-4-√4
39 = 44-√4/0.4
40 = 44-√4-√4
41 = (4!+√4)/0.4-4!
42 = 44-(4-√4)
43 = 44-(4/4)
44 = 44+4-4
45 = 44+(4/4)
46 = 44+(4-√4)
47 = 4!+4!-4/4
48 = 44+√4+√4
49 = 4!+4!+4/4
50 = 44+4+√4
51 = 4!/0.4-4/.4444
52 = 44+4+4
53 = 4!/.4444-4/4
54 = 4!/0.4-4-√4
55 = 4!/.4444+4/4
56 = 4!/0.4-√4-√4
57 <> (4!+√4)/0.4+√4 --> 57 = (4!-√4)/0.4+√4
58 = 4!/0.4-(4-√4)
59 = 4!/0.4-4/4
60 = 4*4*4-4
61 = 4!/0.4+4/4
62 = 4*4*4-√4
63 = (4!+√4)/0.4-√4
64 = (4+4)*(4+4)
65 = (4!+4-√4)/0.4
66 = 4*4*4+√4
67 = (4!+√4)/0.4+√4
68 = 4*4*4+4
69 = 4!/0.4+4/.4444
70 = 4!*4-4!-√4
71 = (4!+4+0.4)/0.4
72 = 4!+44+4
73 = √(√(√(4^4!)))+4/.4444
74 = 4!*4-4!+√4
75 = (4!+4+√4)/0.4
76 = 4!*4-4!+4
77 = 4!/(.4444*√.4444)-4
78 = (4!-4)*4-√4
79 = 4!/(.4444*√.4444)-√4
80 = 4!/0.4+4!-4
81 = (4-4/4)^4
82 = 4!/0.4+4!-√4
83 = 4!/(.4444*√.4444)+√4
84 = 44*√4-4
85 = 4!/(.4444*√.4444)+4
86 = 4!/0.4+4!+√4
87 = 4!*4-4/.4444
88 = 44+44
89 = (4!/√.4444-0.4)/0.4
90 = 4!*4-4!/4
91 = 4!*4-√4/0.4
92 = 4!+4!+44
93 = 4!*4-√4/√.4444
94 = 4!*4-(4-√4)
95 = 4!*4-4/4
96 <> 4!+4!+4!+4! --> 96 = 4!*4+4-4
97 = 4!*4+4/4
98 = 4!*4+4-√4
99 = 4!*4+√4/√.4444
100 = 4!*4+√4+√4
A word of caution to those doing the 9's puzzle... don't type out the answers too quickly, or you'll accidently skip important keystokes, like I did with this puzzle.
