# 90 (float) isn't same as 90 (int)? Atleast not for autoit. It thinks that 90 that is result of aCos is > than just 90.

I am supprised that in 1st test value of \$__ is 90 with out any or. it's exactly 90 but \$__ = 90 returns false. Does anyone know how what causes this problem in my test? for somereason it thinks that \$__ is greater than 90 but when you look at console output you can clearly see that it isn't.

You can run code below.

```MsgBox(0, 0, Test("1 0 2 0 1 2"))
;MsgBox(0, 0, Test("3 0 4 2 5 0"))
;MsgBox(0, 0, Test("6 0 7 0 8 2"))
;~ \$TriangleCoords = "x1 xy x2 y2 x3 y3"
;~ Angles: If 1 of the angles are:
;         < 90 acute angle
;           > 90 obtuse angle
;         = 90 square corner
Func Test(\$TriangleCoords)
ConsoleWrite(@CRLF)

\$Triangle = \$TriangleCoords
\$Triangle = StringSplit(\$Triangle, " ")

Dim \$A[2], \$B[2], \$C[2], \$AB[2], \$BC[2], \$CA[2]

\$A[0] = Number(\$Triangle[1])
\$A[1] = Number(\$Triangle[2])

\$B[0] = Number(\$Triangle[3])
\$B[1] = Number(\$Triangle[4])

\$C[0] = Number(\$Triangle[5])
\$C[1] = Number(\$Triangle[6])

\$AB[0] = \$B[0] - \$A[0]
\$AB[1] = \$B[1] - \$A[1]

\$BC[0] = \$C[0] - \$B[0]
\$BC[1] = \$C[1] - \$B[1]

\$CA[0] = \$A[0] - \$C[0]
\$CA[1] = \$A[1] - \$C[1]

\$A = Sqrt(\$AB[0] ^ 2 + \$AB[1] ^ 2)
\$B = Sqrt(\$BC[0] ^ 2 + \$BC[1] ^ 2)
\$C = Sqrt(\$CA[0] ^ 2 + \$CA[1] ^ 2)

\$pi = 3.14159265358979323846264338327950288419716939937510

\$_ = ACos((\$B ^ 2 + \$C ^ 2 - \$A ^ 2) / (2 * \$B * \$C)) * \$radToDeg
\$__ = ACos((\$A ^ 2 + \$C ^ 2 - \$B ^ 2) / (2 * \$A * \$C)) * \$radToDeg
\$___ = ACos((\$A ^ 2 + \$B ^ 2 - \$C ^ 2) / (2 * \$A * \$B)) * \$radToDeg

ConsoleWrite(\$_ & @CRLF)
ConsoleWrite(\$__ & @CRLF)
ConsoleWrite(\$___ & @CRLF)

MsgBox(0,\$__,\$__ = 90)

;If \$_ = 90 or \$__ = 90 Or \$___ = 90 Then Return "Täisnurk"
;If \$_ > 90 or \$__ > 90 Or \$___ > 90 Then Return "nürinurk"

EndFunc   ;==>Test```

I figured that when I change \$__ = 90 to String(\$__) = String(90) then it returns true

you can use string comparation

\$__ == 90

or

Int(\$__) = 90

There are those that believe that the perfect heist lies in the preparation.
Some say that it’s all in the timing, seizing the right opportunity. Others even say it’s the ability to leave no trace behind, be a ghost.

just wondering why it doesnt work with numbric versions of variables? Is it because 1 is float and other is int?

Because ACos(...) * 180 / 3.14... <> 90 and Pi <> 3.14159265358979323846264338327950288419716939937510. Am I right? For a correct comparison of the values ​​you need to round a float value with an accuracy of its type. For the FLOAT type it should be about seven digits, DOUBLE - about 15 digits.

`MsgBox(0, \$__, Round(\$__, 7) = 90)`

Try this:

```\$Num = 1
For \$i = 0 To 100
\$Num += 0.1
ConsoleWrite(\$Num & @CRLF)
Next```

Instead of using the long floating number for pi just use

`Const \$pi = ACos(-1)`
