浮点数转换成十六进制(用python转换浮点数为16进制怎么写？比如把34.4536或者-34.4536转成16进制)

# -*- coding: utf8 -*-import ctypesdef h2f(s): cp = ctypes.pointer(ctypes.c_longlong(s)

) fp = ctypes.cast(cp, ctypes.POINTER(ctypes.c_double)

) return fp.contents.valuedef f2h(s): fp = ctypes.pointer(ctypes.c_double(s)

) cp = ctypes.cast(fp, ctypes.POINTER(ctypes.c_longlong)

) return hex(cp.contents.value)print(f2h(34.4536)

)print(h2f(0x40413a0f9096bb99))
