Fixreal is a set of functions to convert numbers between fixed and floating point representation as experienced by simulink users. It permits conversion of 8, 16 and 32 bit representation of signed and unsigned decimal numbers, with or without binary point. INSTALLATION ============ Package can be downloaded from the public git repo as:: $ git clone git://github.com/flyingfrog81/fixreal.git $ python setup.py install or installed automatically via pypi:: $ pip install fixreal USAGE ===== >>> import fixreal >>> fixreal.real2fix(-0.9921875, fixreal.get_conv(8, 7, True)) 129.0 >>> fixreal.real2fix(-3.96875, fixreal.get_conv(8, 5, True)) 129.0 >>> fixreal.real2fix(-127, fixreal.get_conv(8, 0, True)) 129.0 >>> fixreal.real2fix(1.0078125, fixreal.get_conv(8, 7, False)) 129.0 >>> fixreal.real2fix(4.03125, fixreal.get_conv(8, 5, False)) 129.0 >>> fixreal.real2fix(129, fixreal.get_conv(8, 0, False)) 129.0 >>> fixreal.fix2real(0b10000001, fixreal.get_conv(8, 7, True)) -0.9921875 >>> fixreal.fix2real(0b10000001, fixreal.get_conv(8, 5, True)) -3.96875 >>> fixreal.fix2real(0b10000001, fixreal.get_conv(8, 0, True)) -127.0 >>> fixreal.fix2real(0b10000001, fixreal.get_conv(8, 7, False)) 1.0078125 >>> fixreal.fix2real(0b10000001, fixreal.get_conv(8, 5, False)) 4.03125 >>> fixreal.fix2real(0b10000001, fixreal.get_conv(8, 0, False)) 129.0 >>> conv = fixreal.conv_from_name("fix_8_7")
