I'm trying to integrate over normal distribution for some numbers, but some inputs are giving weird results
> round(integrate(dnorm, mean=322.3037, sd=18.96672, lower= 86, upper= Inf,abs.tol = 0L)$value*100,0)
[1] 100
> round(integrate(dnorm, mean=322.3037, sd=18.96672, lower= 85, upper= Inf,abs.tol = 0L)$value*100,0)
[1] 0
Why the second result is giving 0, when should be giving 100 as the first one?
