Difference between float and decimal data type
...most environments is a binary floating-point type. It can accurately store base-2 values (to a certain point), but cannot accurately store many base-10 (decimal) values. Floats are most appropriate for scientific calculations. They're not appropriate for most business-oriented math, and inappropriat...

operator sizeof should evaluate to a
constant value that is compatible with
size_t.
As an implication, size_t is a type guaranteed to hold any array index.
