texte = A while ago there was some discussion about using [math]ceil([RANDOM format=float]*(randomrange))[/math] to get a random number. We were just trying this and came up with an anomaly: including the occasional negative number!!! (and the negative number always is in the range -480 to -490ish.Here's our code. It looks for a RANDOM no up to 99 over 50,000 loops, and counts the number of occurences of 1, numbers in the 90s, 0, and less than zero.[math show=f]one_count=0[/math] [math show=f]ninety_count=0[/math] [math show=f]zero_count=0[/math] [math show=f]minuszero_count=0[/math][loop start=1&end=50000&advance=1] [text show=f]random_number=[math]ceil([RANDOM format=float]*(99))[/math][/text] [!][showif [random_number]<1][index].
