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 = 1.1921e-07 --> 1.0f+eps ans = 1
