floating point - Java: How to convert a String of Binary values to a Float and vice-versa?

Question

How do I convert the float value of 12345.12346f to a String of binary values, i.e. "0011010101010101", and vice-versa?

Answer 1

I'm not sure it is what you want, but here's a solution to have the binary representation of the IEEE 754 floating-point "double format" bit layout for a float (it is basically the memory representation of a float) :

int intBits = Float.floatToIntBits(yourFloat); 
String binary = Integer.toBinaryString(intBits);

For the reverse procedure :

int intBits = Integer.parseInt(myString, 2);
float myFloat = Float.intBitsToFloat(intBits);
