Input:

An equation.

 

 

 

 

 

Output:

Level 2/Item 1: The expression to the left of the “=” sign in the original equation, or, if the input

 

is an expression and not an equation, the independent variable.

 

Level 1/Item 2: The expression to the right of the “=” sign in the original equation, or, if the

 

input is an expression, the expression.

 

 

Flags:

Numeric mode must not be set (flag –3 clear).

 

 

 

In Algebraic mode (flag –95 set), the output expressions are evaluated (variables are replaced by

 

numeric values) before the result is returned.

 

 

Example:

Split the following equation into its two component expressions: sin(x)=5x+y

Command:

EXLR(SIN(X)=5*X+Y)

 

 

 

 

Result:

{SIN(X), 5*X+Y}

EXP

Analytic Function

 

 

 

 

 

Type:

 

 

 

 

 

Description:

Exponential Analytic Function: Returns the exponential, or natural antilogarithm, of the

 

argument; that is, e raised to the given power.

 

 

 

EXP uses extended precision constants and a special algorithm to compute its result to full 12-

 

digit precision for all arguments that do not trigger an underflow or overflow error.

 

EXP provides a more accurate result for the exponential than can be obtained by using e Q.

 

The difference in accuracy increases as z increases. For example:
