[issue46444] Wrong value of pi for larger values using math.cos() function

Darshan Kanade added the comment: The issue is that pi = k*math.cos(math.radians((90 - 180/k))) is giving wrong answer(289.384326...) for larger values of k, say k=2**62, but for smaller values say, k=100 it is giving correct answer(3.14) pi = k*math.sin(math.radians(180/k)) on the
