Returns feps, which quantifies the relative machine precision
of floating point numbers (a machine specific quantity). The syntax
for feps is:
y = feps
which returns feps for single precision values. For most
typical processors, this value is approximately 2^-24, or 5.9604e-8.
The following example demonstrates the use of the feps function,
and one of its numerical consequences.
--> feps
ans =
<float> - size: [1 1]
5.9604645e-08
--> 1.0f+eps
ans =
<double> - size: [1 1]
1.000000000000000
