denormalmax

Return the largest denormalized quantized number for a quantizer

Syntax

• x = denormalmax(q)
  

Description

x = denormalmax(q) is the largest positive denormalized quantized number where q is a quantizer. Anything larger than x is a normalized number. Denormalized numbers apply only to floating-point format. When q represents fixed-point numbers, this function returns eps(q).

Examples

• q = quantizer('float',[6 3]); 
  x = denormalmax(q) 
  

returns the value x = 0.1875 = 3/16.

Algorithm

When q is a floating-point quantizer, denormalmax(q) = realmin(q) - denormalmin(q).

When q is a fixed-point quantizer, denormalmax(q) = eps(q).
