Mathematical and Numerical Constants
The following table includes the built-in mathematical and numerical constants. The names of these constants are reserved names. You cannot use such reserved constant names when creating user-defined variables and parameters.
Table 5-5: Mathematical and Numerical Constants
Name
Description
eps
Floating-point relative accuracy (machine epsilon, 2−52 or about 2.2204·10−16, for double floating-point numbers).
i, j
Imaginary unit, .
inf, Inf
Infinity, ∞. A value larger than what can be handled with floating-point representation. Use the isinf and isnan operators to test if expressions are evaluated as infinity or not-a-number, respectively.
NaN, nan
Not-a-number. An undefined or unrepresentable value such as the result of 0/0 or inf/inf.
pi
Pi (about 3.141592653589793).
