A double-precision floating-point number.
Floating-point operations return NegativeInfinity to signal an overflow condition.
The following example illustrates the use of IsNegativeInfinity:
// This will return "true". outputBlock.Text += String.Format("IsNegativeInfinity(-5.0 / 0) == {0}.", Double.IsNegativeInfinity(-5.0 / 0) ? "true" : "false") + "\n"; ... if (d > Double.MaxValue) { outputBlock.Text += "Your number is bigger than a double." + "\n"; } ... // This will equal Infinity. outputBlock.Text += String.Format("10.0 minus NegativeInfinity equals {0}.", (10.0 - Double.NegativeInfinity).ToString()) + "\n";
