The table title is "The available presentation types for floating point and decimal values are:".

This is slightly confusing to me.  Does this mean instances of 'float' and 'decimal' classes?  or 'floating point numbers (floats and decimals)  and integral numbers, sometimes called decimals since usually written with decimal digits'?

Within the table, 'number' refers to whatever the title refers to. So I think adding '(floating point)' would be confusing and wrong, as it excludes 'decimals' whatever they are.  On the other hand, changing 'Fixed point' to 'Fixed point notation', in parallel with 'Exponential notation', is correct and should be helpful.
