Memory allocation is an operating system specific thing. Why do you NEED to know?

Of course we know that it is 32 bits.
basic
boolean
byte
SCrunched = 16
short
char
IFfy = 32
integer
float
Loaded = 64
long
double

Here are the lines from jni.h -->
typedef float jfloat;
So, I would imagine the memory representation is that the most significant bit is the sign bit followed by the 31 bits for the number.

I am still confused as to WHY you need to know the details of the implementation.
I still do not understand what problem that you are having.
