Whole and not whole numbers...

[Externet]

Greetings. 

Since high school chemistry, learned the formulas of compounds always using whole numbers.

What is this way of subscript ? --->   ...showed that GdSi₂Ge₂ and LaFe_11.384Mn_0.356Si_1.26H_1.52 had TEWIs that were always lower...

Never seen before; can anyone explain ?   (text copied from a website)
