Floating point question

Hi

Dont know if this is the appropriate section..

What is the IEEE-754 binary representation for a 32-bit floatingpoint value and explain how the value is interpreted.

What is the valid range of negative and positive values in 2n x 1.f format that can be supported
in 32 bit floating-point format in accordance with IEEE-754 and how do i convert them to 10n exponent format to give me the complete decimal range?

New to these tems

Thanks

Did you already read about IEEE-754 binary representation, for example here?

I had a read through it and tried to make sense of this but i seem to be getting further away.. this may be a simple problem but this just is clicking with me..

Would 2^-126 and 2^127 be the valid range for positve and negetive? I dont seem to be undersatnding the format of 2n*1.f.

and how would i represent them in 10n format..

sorry
just confused
