Exception for Exp of sum of logs

Specification

Math

\[\begin{array}{l} \\ e^{\log a + \log b} \end{array} \]

FPCore

(FPCore (a b) :precision binary64 (exp (+ (log a) (log b))))

C

double code(double a, double b) {
	return exp((log(a) + log(b)));
}

Fortran

real(8) function code(a, b)
    real(8), intent (in) :: a
    real(8), intent (in) :: b
    code = exp((log(a) + log(b)))
end function

Java

public static double code(double a, double b) {
	return Math.exp((Math.log(a) + Math.log(b)));
}

Python

def code(a, b):
	return math.exp((math.log(a) + math.log(b)))

Julia

function code(a, b)
	return exp(Float64(log(a) + log(b)))
end

MATLAB

function tmp = code(a, b)
	tmp = exp((log(a) + log(b)));
end

Wolfram

code[a_, b_] := N[Exp[N[(N[Log[a], $MachinePrecision] + N[Log[b], $MachinePrecision]), $MachinePrecision]], $MachinePrecision]

Reproduce

herbie shell --seed 2024261 
(FPCore (a b)
  :name "Exp of sum of logs"
  :precision binary64

  :alt
  (! :herbie-platform default (* a b))

  (exp (+ (log a) (log b))))
