Table 11-33 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:
[ISOC99] ISO C (1999) |
[LSB] ISO/IEC 23360 Part 1 |
[SUSv3] ISO POSIX (2003) |
[SVID.3] SVID Issue 3 |
An LSB conforming implementation shall provide the architecture specific functions for Math specified in Table 11-34, with the full mandatory functionality as described in the referenced underlying specification.
