[issue4139] Major error in cmath routines

2008-10-17 Thread thor222
New submission from thor222 <[EMAIL PROTECTED]>: There's an error in the way cmath computes the inverse sine, cosine and tangent functions. Example: In 2.6: cmath.asin(2) returns 1.5707963267948966+1.3169578969248166j However, the answer should be 1.5707963267948966-1.316957
