Dendro  5.01
Dendro in Greek language means tree. The Dendro library is a large scale (262K cores on ORNL's Titan) distributed memory adaptive octree framework. The main goal of Dendro is to perform large scale multiphysics simulations efficeiently in mordern supercomputers. Dendro consists of efficient parallel data structures and algorithms to perform variational ( finite element) methods and finite difference mthods on 2:1 balanced arbitary adaptive octrees which enables the users to perform simulations raning from black holes (binary black hole mergers) to blood flow in human body, where applications ranging from relativity, astrophysics to biomedical engineering.

◆ mul()

static diyfp nlohmann::detail::dtoa_impl::diyfp::mul ( const diyfp &  x,
const diyfp &  y 
)
inlinestaticnoexcept

returns x * y

Note
The result is rounded. (Only the upper q bits are returned.)

◆ normalize()

static diyfp nlohmann::detail::dtoa_impl::diyfp::normalize ( diyfp  x)
inlinestaticnoexcept

normalize x such that the significand is >= 2^(q-1)

Precondition
x.f != 0

◆ normalize_to()

static diyfp nlohmann::detail::dtoa_impl::diyfp::normalize_to ( const diyfp &  x,
const int  target_exponent 
)
inlinestaticnoexcept

normalize x such that the result has the exponent E

Precondition
e >= x.e and the upper e - x.e bits of x.f must be zero.

◆ sub()

static diyfp nlohmann::detail::dtoa_impl::diyfp::sub ( const diyfp &  x,
const diyfp &  y 
)
inlinestaticnoexcept

returns x - y

Precondition
x.e == y.e and x.f >= y.f
