The dots over i and j are called tittles. This is what wikipedia says:The tittle first appeared in Latin manuscripts in the 11th century, to distinguish the letter i from strokes of nearby letters. Although originally a larger mark, it was reduced to a dot when Roman-style typefaces were introduced.The 'u' or 'j' with two dots over are used in some languages,hungarian, Portuguese, to represent a different vowel sound to the English sound.I think they represent a vowel that is more 'fronted' than the English vowel.

10 is two lines 11 is one dot over two lines 12 is two dots over two lines etc... 20 is one dot over a shell. 21 is one dot over one dot 22 is one dot over two dots etc... 39 is one dot over four dots over three lines 40 is two dots over a shell 41 is two dots over one dot 42 is two dots over two dots etc... 60 is three dots over a shell etc... 80 is four dots over a shell etc... 100 is a line over a shell The Mayan number system is a base-20 system. A dot is 1, a line is 5, and up to 19 you can write in one "digit". As soon as the number increases over 20, it goes up into the second "digit" and you stack a dot (this time multiplied by 20) over a shell shape (worth zero). It's just like our number system, except our number system uses a base-10 system.

If there is one dot over the 0 and one over the 7 then it indicates a recurring decimal. for example 6.07 with a dot over the 0 and 7 would be 6.07070707... It the two dotted numbers are further apart, the the sequence between them is repeated. For example, 6.01237 with a dot over the 0 and 7 is 6.012370123701237... But I have yet to come across a double dot over ONE number.
