Type: Function
Description: Degrees to Radians Function: Converts a real number representing an angle in degrees to its
equivalent in radians.
This function operates independently of the angle mode.

e
Type: Function
Description: e Function: Returns the symbolic constant e or its numerical representation, 2.71828182846.
The number returned for e is the closest approximation to 12-digit accuracy. For exponentiation,
use the expression EXP(x) rather than e^x, since the function EXP uses a special algorithm to
compute the exponential to greater accuracy. Even though the calculator often displays EXP(x) as
e^x, it's still' EXP(x)' intenally.
