Member Function Documentation

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.)

Definition at line 14488 of file json.hpp.

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

Definition at line 14553 of file json.hpp.

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.

Definition at line 14570 of file json.hpp.

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
