In floating point representations , how to determine what is to be subtracted from the exponent ?
In 32 bit representation, somewhere it is said to subtract 128 from the exponent, somewhere it is written 127 to be subtracted ?
How to check this ?

With the Excess K information.
It must be given that , "Exponent is represented in Excess K format".
Eg. Excess 127 format demands subtraction of 127
0
what if excess value is not given ?
0
Something would be given , single precision , double precision .
If nothing is given at all , then I think 2s complement representation might be only choice

[COA] Floating point arithmetic
IEEE 754 32 bit representation for reference: 1. For the demoralized numbers,why the exponent is 126 and not 127? For 0 we say it is Mantissa=0 and B.E=0, so we get 0*2^0127=0,but for any number that is having bias exponent ... 128) comes under overflow and underflow condition.I mean if i am 0 or infinity or NAN then can i say that system is overflow/underflow?
