How float number 0.0f represented in memory

Question

I know that decimal numbers are represented in floating point format. every float represented as m2^e where m is mantissa and e is the exponent.

But am not able to find the 0.0f representation.Please provide the steps to get the 0.0f memory representation.

Answer 1

0, inf, nan, are special values, since their mantissa and exponent cannot be derived. They have defined bit patterns:

 0 = 0 00000000 00000000000000000000000
-0 = 1 00000000 00000000000000000000000
