Talking down to the reader is broadly accepted on this site. It's the Free Software business model: you can't get paid for giving advice here, but by providing code or advice, you can earn the privilege of condescending to or verbally abusing people. See the linux-kernel mailing list or the #perl IRC channel for more examples.

    That really is quite funny, but surely the point of this tutorial is to attract new users not to exercise your (well earned) privileges. Though I don't have a problem with 'we' and 'us', all in it together and all that.

[pryrt]: 1nickt, sprintf "%.16e", $v will always give enough precision to see 1 ULP (the smallest fractional part) of a standard 64bit Perl NV*
[pryrt]: (*: for systems where $Config{nvsize}==8 )
[pryrt]: Thus, that's "enough precision" to tell the difference between 1.0 and 1.0+1ULP
[pryrt]: But in what circumstance does your problem arise? When, in Perl, does the integer 1 not work identically to the floating-point NV 1.0000000000000000 e0?
