description C library for multiple-precision floating-point \
|
|
computations
|
|
long_description MPFR is a portable C library for arbitrary-precision \
|
|
binary floating-point computation with correct \
|
|
rounding, based on the GMP multiple-precision \
|
|
library. The computation is both efficient and \
|
|
has a well-defined semantics. It copies the good \
|
|
ideas from the ANSI/IEEE-754 standard for \
|
|
fixed-precision floating-point arithmetic.

|
|
# Due to radr://10291355 (llvm.org PR11111), the new tls support enabled in clang with Xcode 4.2
|
|
# miscompiles mpfr. While this was fixed in Xcode 4.2.1, as the ttls support was never used prior to
|
|
# Xcode 4.2, the generic fix is to pass --disable-thread-safe to configure, however this will break
|
|
# any project that requires a thread-safe mpfr library, therefore the Xcode 4.2 compiler is
|
|
# blacklisted here
