| 123456789101112131415 | Steps to validate transcendental functions:1) Add a file 'umath-validation-set-<ufuncname>', where ufuncname is name of   the function in NumPy you want to validate2) The file should contain 4 columns: dtype,input,expected output,ulperror    a. dtype: one of np.float16, np.float32, np.float64    b. input: floating point input to ufunc in hex. Example: 0x414570a4       represents 12.340000152587890625    c. expected output: floating point output for the corresponding input in hex.       This should be computed using a high(er) precision library and then rounded to       same format as the input.    d. ulperror: expected maximum ulp error of the function. This       should be same across all rows of the same dtype. Otherwise, the function is       tested for the maximum ulp error among all entries of that dtype.3) Add file umath-validation-set-<ufuncname> to the test file test_umath_accuracy.py   which will then validate your ufunc.
