Angle degree values to decimal values

Question

Hi,

I am passing the degree values in the form of "123:09:89".I want to convert this value into its exact decimal value.please suggest any solutions.

 

Answer 1

Is the degree measurement in degrees, minutes, seconds? If so, then use 60 as your divisor.

123 + (9/60) + (89/ 60/ 60)

123 + .15 + .024722

123:09:89 -> 123.174722

In a more general formula:

result = degrees + (minutes/60) + (seconds/60/60)

There is a degree converter site here to use for testing your results:

Hope this helps.

Answer 3

I very rarely make this kind of post, but ...

 

I can understand that you may simply have made a typing mistake in your

first post, when giving an example of a degree with more than 60 seconds,

but if you can't code up basic arithmetic, I wonder if it was such a mistake

or if you simply don't have a proper understanding of what you are doing.

Many people offer help here of their own free will, and at no cost, but this

is not a place to get your work done for you. I would say you are way out of

your depth and should ask your manager for some training because you will

certainly fail when you have do something more complex.

Answer 4

I agree Tony. And LOL on the 89. I was so focused on the code I did not look closely at the example.

And Chi ... you should be able to just paste in the line I provided with the variables (result = ...). The only other thing you need to do is to declare the variables.

These are elementary tasks in any language.

Hope this helps.

Answer 6

Hi Deborah K,

U already suggested me solution to convert a dms value to degree.The problem in that is i am getting the dms value from RS232 cable. The value is in string format. I am splitting the string. My problem is when i get negative dms values then i should get negative decimal value. the suggestion which u provided is fine for for ordinary dms values.

i will explain u with examples,

for -158:02:00 it is -158.033333

and for 0:01:00 and -0:01:00 is -0.01666 and my code as follows

If

 

(no.Contains(":") = True) Then

 

d = CDbl(de(0))

m =

CDbl(de(1))

s =

CDbl(de(2))

d1 =

CDbl(su(0))

m1 =

CDbl(su(1))

s1 =

CDbl(su(2))

 

 

 

If d > 0 Then

mddms = d + (m / 60) + (s / 60 / 60)

 

Else

mddms = Math.Abs(d) + (m / 60) + (s / 60 / 60)

mddms = -mddms

 

End If

End If.

u r help is most welcomed.
