...function is very slow due to using mpfr, but i believe accurate to the accuracy of genhypergeo() which it uses - 14-15 dp. LargeRangeDiffdf150.png, which is difference between dt() and my function, shows spikes across -1.5 < x < 1.5. I assumed probably only a problem for large df, but SmallRangeCloseZerodf20.png, shows actually more of a problem with df = 20.? Accuracy seems to be only to 6 decimal places. Using R version 3.5.2.
