Fixed dead link on Wikipedia, corrected horrific mistake (1 + 12 + 52 != 64), and used a non-mobile wiki URL

Explain the rounding method used instead of glossing over it by saying it's rounded away from zero (which in general is not quite true).

State how zeros are represented and explicitly state that they are not denormal (instead, they form a separate class along with NaN values, infinities, normals, and denormals)

Make explicit how denormal numbers have an implied zero.

Make explicit how denormal supports representing zero.

Corrected comment on subnormal numbers. The largest subnormal number is not 2^-1023 (which has an offset exponent of 0 and mantissa 1000...000). Instead, it is 2^(-1023 + 1) - 2^(-1023 - 51), which has an offset exponent of 0 and mantissa 1111...111.
