Certainly! I have had the honor of training with two of them, both natives of Okinawa.
There is no such thing as a tenth degree black belt.
The answer depends on the degree of rounding. To the nearest tenth (or smaller) it is 1 tenth. To the nearest unit (or bigger) it is 0.
You leave it exactly as it is. Do nothing. 64.4, rounded to the nearest tenth is 64.4.
There are two major levels in Karate and most Japanese based martial arts. The first are the beginners, the Kyu (Japanese) or Gup (Korean) students. Typically these are indicated by different colored belts and in general run from lighter to darker colors as one gets more knowledge and skill. Then there are the Dan levels, or the black belts. There are 10 levels of these from First Degree Black Belt to Tenth Degree. In most styles the first 6 levels of black belt are really black. Seven and Eighth wear a red and white striped belt and Ninth and Tenth wear a solid red belt.
No Use, atleast have a degree behind for better career.
The angle would be .4 if you rounded it to the nearest 10th degree
As an integer, it is already rounded to the nearest tenth.
The angle would be 82.4053 degrees, or 82.4 correct to the nearest tenth of a degree.
If that's 12 degrees, it's 12.0
8947.0
Runways
It is already rounded to a greater degree than that!
