realmin - Smallest positive normalized fixed-point value or quantized number
Syntax
realmin(a)
realmin(q)
Description
realmin(a) is the smallest real-world value
that can be represented in the data type of fi object a.
Anything smaller underflows.
realmin(q) is the smallest positive normal
quantized number where q is a quantizer object.
Anything smaller than x underflows or is an IEEE "denormal"
number.
Examples
q = quantizer('float',[6 3]);
x = realmin(q)
x =
0.2500
Algorithm
If q is a floating-point quantizer object,
where
is the minimum
exponent.
If q is a signed or unsigned fixed-point quantizer object,
where f is
the fraction length.
