Double.doubleToLongBits() method uses

This method can convert double type data into long type data, so that the double type data can be judged according to the long method (<,>, ==).

Example:

1. Double.doubleToLongBits(10.00) == Double.doubleToLongBits(10.00)

2. Double.doubleToLongBits(20.00) > Double.doubleToLongBits(10.00)

3. Double.doubleToLongBits(10.00) < Double.doubleToLongBits(20.00)

Syntax:

Syntax

 public static double longBitsToDouble(long bits_rep);

Parameter(s):

Parameters:

• long bits_rep – represents the long integer value.

  long bits_rep – represents the long integer value.

Return value:

Return value:

The return type of this method is double, it returns the bits that represent the long integer value.

The return type of this method is double, which returns the bits representing the long value.

Note:

Note:

• If we pass "0x7ff0000000000000L", it returns the value "positive infinity".

  If we pass "0x7ff0000000000000L" which will return the value "positive infinity".

• If we pass "0xfff0000000000000L", it returns the value "negative infinity".

  If we pass "0xfff0000000000000L" which will return the value "negative infinity".
