Brian Brazil	4c8173acac	Use timestamp of a sample in deriv() to avoid FP issues (#2958) ... With the squaring of the timestamp, we run into the limitations of the 53bit mantissa for a 64bit float. By subtracting away a timestamp of one of the samples (which is how the intercept is used) we avoid this issue in practice as it's unlikely that it is used over a very long time range. Fixes #2674	2017-08-07 17:15:38 +01:00
beorn7	71571a8ec4	promql: Fix (and simplify) populating iterators ... This was only relevant so far for the benchmark suite as it would recycle Expr for repetitions. However, the append is unnecessary as each node is only inspected once when populating iterators, and population must always start from scratch. This also introduces error checking during benchmarks and fixes the so far undetected test errors during benchmarking. Also, remove a style nit (two golint warnings less…).	2016-08-24 18:37:09 +02:00
