7.3.9 Hardware decimal floating point

Industry support for decimal floating point is growing, with IBM leading the open standard
definition. Examples of support for the draft standard IEEE 754r include Java BigDecimal, C#,
XML, C/C++, GCC, COBOL, and other key software vendors, such as Microsoft and SAP.
Decimal floating point support was introduced with z9 EC. z13s inherited the decimal floating
point accelerator feature that was introduced with z10 EC. For more information, see 3.4.6,
"Decimal floating point accelerator" on page 96.
Table 7-12 lists the operating system support for decimal floating point. For more information,
see 7.6.6, "Decimal floating point and z/OS XL C/C++ considerations" on page 291.

7.3.10 Up to 40 LPARs

This feature, first made available in z13s, allows the system to be configured with up to 40
LPARs. Because channel subsystems can be shared by up to 15 LPARs, you must configure
three channel subsystems to reach the 40 LPARs limit. Table 7-13 lists the minimum
operating system levels for supporting 40 LPARs.
