What's the matter with G25???

[leachim_x]

The coordinates contains negative values and also letters.

1 random example:
"...-6.8E-05"

Is G25 even based on regions? (i don't think so) i can't find nothing.

So that are K13 regions:
Amerindian Arabian Armenian Basque Central_African Central_Euro East_African East_Asian East_Balkan East_Central_Asian East_Central_Euro East_Med Eastern_Euro

So whats the matter with g25?
I hope this doesn't turn out to be so mathematically abstract...

6.8e+05 is a scientific notation used in mathematics, physics, chemistry, astronomy and other sciences to handle either very large or very small numbers. With scientific notation adding, subtracting, multiplying and dividing numbers becomes much simpler.

I'm not a mathematician! :picard1: I never saw values like this in k13,k15,k36 or any other other calculator from eurogenes, MDLP, Dodecat or whatever. Neither i saw negative numbers.

I just recognized that G25 seems to be different from other tools and asking here to learn and understand it a little bit.
But thanks for explaining this little fragment to me.

Because the G25 are the coordinates of a PCA, they are not components like in the k15

Its nothing special, -6.8E-05 just means -6.8 x 10^-5 (or just -0.000068), and E stands for exponent

Aaaah, i wasn't aware of this syntax. Although i had seen it before. But i remember now. That's totally logic :) thank you

Yes, it is. Thx also :) Now i have some basic knowledge of it.

Thx both of you. That really helped me a lot:thumb001::thumb001:
