imho, the computation for Pi as shown actually computes only Pi/2[edit]

The algorithm as shown to compute an approximation of Pi actually computes imo in this form only Pi/2, even while the output shown contains an approximation for Pi. I think either the values should be halved or the formula should be changed into : 12 * 2^i * t_i KeesLem (talk) 15:16, 21 February 2013 (UTC) — Preceding unsigned comment added by 130.161.210.156 (talk)

Zuse's Z3 floating-point format[edit]

There are contradictory documents about the size and the significand (mantissa) size of the floating-point format of Zuse's Z3. According to Pr Horst Zuse, this is 22 bits, with a 15-bit significand (implicit bit + 14 represented bits). There has been a recent anonymous change of the article, based on unpublished Raúl Rojas's work, but I wonder whether this is reliable. Raúl Rojas was already wrong in the Bulletin of the Computer Conservation Society Number 37, 2006 about single precision (he said 22 bits for the mantissa).

Error in diagram[edit]

The image "Float mantissa exponent.png" erroneously shows that 10e-4 is the exponent, while the exponent actually is only -4 and the base is 10. — Preceding unsigned comment added by 109.85.65.228 (talk) 12:14, 22 January 2014 (UTC)

needs simpler overview[edit]

put it this way, I'm an IT guy and I can't understand this article, there need to be a much simpler summery for non tech people, using simple English. Right now every other word is another tech term I don't fully understand.
