+utilities</b> </p> <p>The maths utilities are a collection of static class
+functions that perform trigonometric, power/root/log, conversion and rounding,
+and test functions on real numbers.</p> <p><b>Extended
+precision real number</b> </p> <p>The extended precision real number type
+provides 64-bit precision, and efficient arithmetic and comparison operators.</p> <p>The
+extended precision real number type is provided by <xref href="GUID-4AF7C5C2-7EB8-39A5-B3E6-75268DB11BD6.dita"><apiname>TRealX</apiname></xref>.</p> </section>
