I've found a very good example of customfloat, but in my computer it can't find CustomFloat function?

Does anyone know the reason(in the web it works;;)

v = pi;
word_length = 16;
mantissa_length = 4;
x = CustomFloat(v, word_length, mantissa_length)
x = 
    3.1250


           Data Type: Floating-point: Custom-precision
          WordLength:  16
      MantissaLength:   4
      ExponentLength:  11
        ExponentBias: 1023

You need the Fixed-Point Designer toolbox, which is a separate product you may not have in your system.

In the web, the toolbox is available.
