Functions
-
int round(double x)
Return rounded double to nearest integer. This rounding is implemented as floor(x+0.5), such that feasstRound(-0.5) == 0. The cplusplus library round(-0.5) from math.h results in round(-0.5) == -1, such that rounding at the halfway point is away from zero. This breaks the first bin on histograms.
