-Some mathematical functions fall back to multiple precision arithmetic for
-some inputs to get last bit precision for their return values. This multiple
-precision fallback is much slower than the default algorithms and may have a
-significant impact on application performance. The systemtap probe markers
-described in this section may help you determine if your application calls
-mathematical functions with inputs that may result in multiple-precision
-arithmetic.
-
-Unless explicitly mentioned otherwise, a precision of 1 implies 24 bits of
-precision in the mantissa of the multiple precision number. Hence, a precision
-level of 32 implies 768 bits of precision in the mantissa.
