What is Exponent field?
The bits of a floating-point number giving the power of two. To represent negative exponents, the true exponent plus a bias (127 for single precision) is stored.
Field: Computer Arithmetic
Exponent field in the explanations
To allow negative exponents, the exponent field stores the true exponent plus a bias.
