Write float to a file using DataOutputStream

/*
Write float to a file using DataOutputStream
This Java example shows how to write a Java float primitive value to a file using
writeFloat method of Java DataOutputStream class.

* To write a float value to a file, use
* void writeFloat(float f) method of Java DataOutputStream class.

* This method writes specified float to output stream as 4 bytes value.
* Please note that the float value is first converted to int using
* Float.floatToIntBits method and then int is written to underlying output
* stream.
