doubleexpx2(	double	`x`

Computes the exponential of a squared argument,

$\exp (x^2)$

while suppressing error amplification that would ordinarily arise from the inexactness of the argument $\inline x^2$ .

x	the argument
sign	the optional sign of the argument. If sign < 0, the result is inverted. i.e. $\inline y= exp(-x^2)$ .
