FixedArctanOf​(System.​Int32)

 Method (no overloads)

Summary

arctan(j/64) in fixed point for sixtyFourths = j from
0 to 64: the arctangent's argument is brought within 1/128 of zero by the
nearest of these, arctan x = arctan c + arctan((x - c)/(1 + xc)). Built
up from arctan 0 = 0 when first asked, one short series a step:
arctan(j/64) - arctan((j - 1)/64) = arctan(64/(4096 + j(j - 1))).
