Converting hex string representation to float in python

Question

I have data in IEEE 745 hexadecimal format: 0x1.5c28f5c28f5c3p-1

How would I convert this to a float in python? is this a standard module?

@Kevin: The "p" is similar to "e" but using a base of 2 instead of 10. — Ignacio Vazquez-Abrams, Nov 30 '15 at 15:55

>>> float.fromhex('0x1.5c28f5c28f5c3p-1')
0.68

It's in the standard library, float.fromhex.

IMO this should be combined with Ignacio's answer and accepted. This lacks code, his lacks a link to the docs. – Two-Bit Alchemist Nov 30 '15 at 15:55
