Method

doubleacosh(double a)
Calculates inverse hyperbolic cosine of a double value. 
return Math.log(Math.sqrt(a * a - 1.0d) + a);
doubleacosh(double x)
acosh 
return Math.log(x + Math.sqrt(x * x - 1));
doubleacosh(double x)
Returns the inverse (arc) hyperbolic cosine of a double. 
double ans;
if (Double.isNaN(x) || x < 1) {
    ans = Double.NaN;
} else if (x < 94906265.62) {
    ans = Math.log(x + Math.sqrt(x * x - 1.0));
} else {
    ans = 0.69314718055994530941723212145818 + Math.log(x);
return ans;
doubleacosh(double x)
