¶int ilogb(const llvm::detail::IEEEFloat& Arg)

Description

Returns the exponent of the internal representation of the APFloat. Because the radix of APFloat is 2, this is equivalent to floor(log2(x)). For special APFloat values, this returns special error codes: NaN -> \c IEK_NaN 0 -> \c IEK_Zero Inf -> \c IEK_Inf

Declared at: llvm/include/llvm/ADT/APFloat.h:446

Parameters

const llvm::detail::IEEEFloat& Arg
