Summary: Math results are compared with MPFR results by checking if they are within a tolerance level of the MPFR result. The tolerance level is set using additional bits of precision of the fractional part of a floating point value. Hence, the actual value of the tolerance depends on not only the additional bits, but also on the exponent part of the floating point number. Previously, the exponent part was not considered in evaluating the tolerance value. While it was OK for small values less than 1 (hence sinf, cosf, sincosf tests were OK), it breaks for large values which functions like exp and friends produce. This change uses the exponent value also to evaluate the tolerance value. LLVM libc produced results can now be compared with MPFR produced results for large values also.
