TheFP_NORMAL,FP_SUBNORMAL,FP_ZERO,FP_INFINITE,FP_NANmacros each represent a distinct category of floating-point numbers. They all expand to an integer constant expression. ConstantExplanation FP_NORMALindicates that the value isnormal, i.e. not an infinity, subnormal, not-a-number or zero ...

A circuit is proposed for floating-point multiplication to minimize the unintentional delay for the holistic support of subnormal numbers. In this proposed four-path FP multiplication, the circuit produces the four types of output in four paths having different delays for all cases of input ...
The far path may include a subtraction circuit for computing the difference between a received exponent value and a minimum exponent value, at least two shifters for shifting far greater and far lesser mantissa values in parallel, and associated circuitry for handling subnormal numbers. The adder ...
The far path circuit may be configured to compute a far path result based upon either the addition or the subtraction of the two floating point numbers regardless of whether the operands or the result include normal or denormal numbers. The close path circuit may be configured to compute a ...
