SpletUse isfloat if you just want to verify that x is a floating-point number. This function returns logical 1 ( true) if the input is a floating-point number, and logical 0 ( false) otherwise: isfloat (x) ans = logical 1. You can convert other numeric data, characters or strings, and logical data to double precision using the MATLAB function, double. SpletEncodes the quantized floating-point value to an integer value. In the first step, the block quantizes an input value to one of 2 B uniformly spaced levels in the range [- V , (1-2 1-B) V ], where you specify B in the Bits parameter and you specify V in the Peak parameter. The quantization process rounds both positive and negative inputs ...
