# DesignScript behaviour compared to python

Hi,

I stumbled upon a difference in behaviour between DesignScript and Python while trying to perform simple mathematical operations. Python yields the correct result (checked in a 3rd party software) while DesignScript produces a non-sense result. I suspect that i use Math library in a wrong way. i attach code in both languages below.
DS:

``````pi = 3.14;
p1 = KarmorR-Kmud-TcoreR-TfilterR;
p2 = Math.Sin(aR2*pi/180);
p12 = p1/p2;
p3 = Math.Tan(aR2*pi/180);
p4 = TarmorR/p3;
p1234 = p12-p4;
p5 = aR3-aR2;
p6 = p5 * pi/180;
p56 = Math.Sin(p6);
p123456 = p1234 * p56;
p7 = aR3*pi/180;
p8 = Math.Sin(p7);
p12345678 = p123456 / p8;
p9 = aR2*pi/180;
p10 = Math.Sin (p9);
p11 = TarmorR/p10;
p1234567891011 = p12345678 + p11;
``````

Python:

``````KarmorR = IN
Kmud = IN
TcoreR = IN
TfilterR = IN
aR2 = IN
TarmorR = IN
aR3 = IN

# Place your code below this line
pi = math.pi
p1 = KarmorR - Kmud - TcoreR - TfilterR
p2 = math.sin(aR2*pi/180);
p12 = p1/p2;
p3 = math.tan(aR2*pi/180);
p4 = TarmorR/p3;
p1234 = p12-p4;
p5 = aR3-aR2;
p6 = p5 * pi/180;
p56 = math.sin(p6);
p123456 = p1234 * p56;
p7 = aR3*pi/180;
p8 = math.sin(p7);
p12345678 = p123456 / p8;
p9 = aR2*pi/180;
p10 = math.sin (p9);
p11 = TarmorR/p10;
p1234567891011 = p12345678 + p11;
# Assign your output to the OUT variable.
OUT = p1234567891011
``````

I am pretty sure I might be using syntax of DS in a wrong way, but I am unable to localize the issue myself. Anyone has suggestion where to look for a solution? Also, I couldn’t find any documentation on Math library, anyone knows if it exists in DS?

Thanks!

Please post screenshots showing the different results

Also change your first line in Design Script to
`pi = Math.PI;`

Here are different results. I have also changed it from 3.14 t Math.PI.

@jevhid You’ll need to convert Radians to Degrees

``````pi = Math.PI;
p1 = KarmorR - Kmud - TcoreR - TfilterR;
p12 = p1/p2;
p4 = TarmorR/p3;
p1234 = p12-p4;
p5 = aR3-aR2;
p6 = p5 * pi/180;
p123456 = p1234 * p56;
p7 = aR3*pi/180;
Thank you for the tip! I knew I was missing something
