• ### Field Detail

• #### E

`public static final double E`
Euler's number e, the base of natural logarithms.
Constant Field Values
• #### PI

`public static final double PI`
Pi, the ratio of the circumference of a circle to its diameter.
Constant Field Values
• #### Infinity

`public static final double Infinity`
Positive infinite floating point value.
Constant Field Values
• #### NaN

`public static final double NaN`
Not-a-Number floating point value. Use with care; arithmetic and logical operations behave in strange ways near NaN (for instance, `NaN!=NaN`). For most purposes this is equivalent to the blank value.
