Syntax

d = Eps()

d = Eps(arg)

d = Eps(‘double’)

Argument

Name

Description

arg

(optional)

The reference value from which to compute the distance to the next larger floating point number. The default is 1.0 in double precision. arg = ‘double’ is the same as the default.

Output

Name

Description

d

The distance from abs(X) to the next larger floating point number with the same precision as the argument (either double precision or single precision).

Example 1

Find the distance to the next number larger than 2.0.

Syntax

d = Eps(2.0)

Result

d = 4.4408920985006e-016
