Description

The list of methods to do Number Copy Sign are organized into topic(s).

Method

doublecopySign(Double magnitude, Double sign)
Copy sign. 
return Math.copySign(magnitude, sign);
doublecopySign(double magnitude, double sign)
copy Sign 
if (sign < 0) {
    return (magnitude < 0) ? magnitude : -magnitude;
} else {
    return (magnitude > 0) ? magnitude : -magnitude;
doublecopySign(double x, double y)
Returns one value with the sign of another (like copysign). 
return y >= 0.0 ? Math.abs(x) : -Math.abs(x);
doublecopySign(final double magnitude, final double sign)
Copies the sign of sign into magnitude. 
final long m = Double.doubleToLongBits(magnitude);
final long s = Double.doubleToLongBits(sign);
if (0 <= (m ^ s))
    return -magnitude;
return magnitude;
doublecopysign(final double x, final double y)
copysign 
return (y < 0.0D && x > 0.0D) ? -x : ((y > 0.0D && x < 0.0D) ? -x : x);
doublecopySign(final double x, final double y)
copy Sign 
return Double.longBitsToDouble((Double.doubleToLongBits(x) & 0x7fffffffffffffffL)
        | (Double.doubleToLongBits(y) & 0x8000000000000000L));
