Java - Float intBitsToFloat(int) method
Description
The Java Float intBitsToFloat() method returns the float value corresponding to a given bit representation. The argument is considered to be a representation of a floating-point value according to the IEEE 754 floating-point "single format" bit layout.It includes the following important points −
- If the argument is 0x7f800000, the result is positive infinity.
- If the argument is 0xff800000, the result is negative infinity.
- If the argument is any value in the range 0x7f800001 through 0x7fffffff or in the range 0xff800001 through 0xffffffff, the result is a NaN.
Declaration
Following is the declaration for java.lang.Float.intBitsToFloat() method
public static float intBitsToFloat(int bits)
Parameters
bits − This is an integer.
Return Value
This method returns the floating-point value with the same bit pattern.
Exception
NA
Example 1
The following example shows the usage of Float intBitsToFloat() method to get a float value from a given bit representation. We've printed three float values based on given bit representations.
package com.tutorialspoint; public class FloatDemo { public static void main(String[] args) { /* returns the float value corresponding to a given bit representation */ System.out.println(Float.intBitsToFloat(6757689)); System.out.println(Float.intBitsToFloat(0x7f800000)); System.out.println(Float.intBitsToFloat(0xff800000)); } }
Output
Let us compile and run the above program, this will produce the following result −
9.469539E-39 Infinity -Infinity
Example 2
The following example shows another usage of Float intBitsToFloat() method to get a float value from a given bit representation. We've printed a float value based on given bit representation.
package com.tutorialspoint; public class FloatDemo { public static void main(String[] args) { /* returns the float value corresponding to a given bit representation */ System.out.println(Float.intBitsToFloat(1098173645)); } }
Output
Let us compile and run the above program, this will produce the following result −
15.3
Example 3
The following example shows the usage of Float intBitsToFloat() method to get a float value from a given bit representation. We've printed a float value based on given bit representations.
package com.tutorialspoint; public class FloatDemo { public static void main(String[] args) { /* returns the float value corresponding to a given bit representation */ System.out.println(Float.intBitsToFloat(-1049310003)); } }
Output
Let us compile and run the above program, this will produce the following result −
-15.3
