base-10 to base-12 conversion

[Constantine Vassilev]

I have following number representing years in base-10 decimal:

10.5 

the meaning is 10 years and half = 10 years and 6 months.

What I need it when I have the number 10.5 which is in base-10 

to be converted to 10.6 which is in base-12. That way I can get 

the whole part which is 10 representing years and decimal part which

is 6 representing months and print it:  10 years and six months.

multiply with 12

I guess he meant 10 + 0.5 *12/10

I got this table:

10	0	0
10	1	1.2
10	2	2.4
10	3	3.6
10	4	4.8
10	5	6
10	6	7.2
10	7	8.4
10	8	9.6
10	9	10.8
		12

According to it 10.5 means 10 years 6 months.

10.6 would mean what? 10 years 7.2 months?

Sorry.. I shouldn't have added the `+` inbetween to avoid misunderstanding.

10 years is 10 * 12 months

0.5 year is 0.5 * 12 months hence 6 months.

The same way, 11 years is (10 + 1) years i.e. 10 years and 1 * 12 months. (but you can't write 10.12 obviously)

Tamas meant for you to multiply the decimal part by 12 to find the remainder in months.

10.5 years is 126 months in base 10. Assuming a notation of A for 10 and B for 11. That would be A6 months in base 12 (10 * 12^1 + 6 * 12^0). What would that be called duodecimal notation? Anyway, that doesn't seem to be what you mean.
