(a) gradient mantissa precision
(b) slow accumulator mantissa precision
(c) weight mantissa precision
(d) exponent scale
so basically you are dropping _only_ LSBs in order of importance and never scale information.

so we store "real" numbers (hahahahahahaha) in something roughly equivalent to scientific notation, like
[sign] [exponent] [mantissa]
which mathematically is
[sign][mantissa] * 2^[exponent]
[sign] [exponent] [mantissa]
which mathematically is
[sign][mantissa] * 2^[exponent]

but we also want to represent infinity, so we say that a number with the maximum representable exponent and zero mantissa is +Inf, and the minimum representable exponent and zero mantissa is -Inf

what, then, do we do with a min/max exponent and nonzero mantissa?
we say it's Not a Number, or NaN.
that gives us 2 * 2^([mantissa bits] - 1) values that are Not a Number

We zijn nogal intiem met sprinkhanen dezer dagen. Een sabelsprinkhaan zat gezellig op schoot vroeg in de ochtend, wenste niet te worden uitgezet. Deze bidsprinkhaan boekte een wellnessnachtje in onze keuken en hing vervolgens drie dagen in de bieslook in de vensterbank.

a 64 bit float is
1 bit sign
10 bit exponent
53 bit mantissa
so you can store integers as
sign = 0 or 1
exponent = 0
mantissa = whatever you want
and the range is +/- 2^53 - 1
1 bit sign
10 bit exponent
53 bit mantissa
so you can store integers as
sign = 0 or 1
exponent = 0
