Detailed Description

Represents a target value in both 256-bit hash form and compact form.

31 0 Format of the compact form: eeeeeeeesmmmmmmmmmmmmmmmmmmmmmmm

e is an 8-bit exponent (0 <= e <= 0x1d), s is a sign bit and m is a 23-bit unsigned mantissa (0 <= m <= 0x7fffff). The value represented by the compact form is m * 256^(e-3). Note that since the target value is always positive, s is always 0.
