Python parse output from Java Double.toHexString(double)

Question

is there a possibility to parse in Python a string that was written from a Java Double.toHexString method?

http://docs.oracle.com/javase/7/docs/api/java/lang/Double.html#toHexString(double)

The output looks like this: '0x1.16d6b97e718ffp8' ... not sure, whether this is a standardized format.

I would expect something like

value=float('0x1.16d6b97e718ffp8')

That'd be float.fromhex:

>>> float.fromhex('0x1.16d6b97e718ffp8')
278.8387679126026

From the docs:

This syntax is similar to the syntax specified in section 6.4.4.2 of the C99 standard, and also to the syntax used in Java 1.5 onwards. In particular, the output of float.hex() is usable as a hexadecimal floating-point literal in C or Java code, and hexadecimal strings produced by C’s %a format character or Java’s Double.toHexString are accepted by float.fromhex().
