Table 14-38 defines the library name and shared object name for the libm library
The behavior of the interfaces in this library is specified by the following specifications:
[LSB] This Specification |
[SUSv3] POSIX 1003.1-2001 (ISO/IEC 9945-2003) |
[SUSv4] POSIX 1003.1-2008 (ISO/IEC 9945-2009) |
An LSB conforming implementation shall provide the generic functions for Math specified in Table 14-39, with the full mandatory functionality as described in the referenced underlying specification.
