[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?
