# varNameString
Refers to the variable whose name is varNameString. This lets you
use strings to create variable names from within a function.
Creates or refers to the variable xyz .
Returns the value of the variable (r) whose name is stored in
variable s1.
E
(scientific notation)
i key
mantissaEexponent
Enters a number in scientific notation. The number is interpreted as
mantissa × 10
exponent
.
Hint: If you want to enter a power of 10 without causing a decimal
value result, use 10^integer.
Note: You can insert this operator from the computer keyboard by
typing @E. for example, type 2.3@E4 to enter 2.3E4.
g
(gradian)
¹ key
Expr1
g
⇒ expression
List1
g
⇒ list
Matrix1
g
⇒ matrix
This function gives you a way to specify a gradian angle while in the
Degree or Radian mode.
In Radian angle mode, multiplies Expr1 by p/200.
In Degree angle mode, multiplies Expr1 by g/100.
In Gradian mode, returns Expr1 unchanged.
Note: You can insert this symbol from the computer keyboard by
typing @g.
In Degree, Gradian or Radian mode:
R(radian)
¹ key
Va lu e1 R ⇒ value
List1R ⇒ list
Matrix1R ⇒ matrix
This function gives you a way to specify a radian angle while in
Degree or Gradian mode.
In Degree angle mode, multiplies the argument by 180/p.
In Radian angle mode, returns the argument unchanged.
In Gradian mode, multiplies the argument by 200/p.
Hint: Use R if you want to force radians in a function definition
regardless of the mode that prevails when the function is used.
Note: You can insert this symbol from the computer keyboard by
typing @r.
In Degree, Gradian or Radian angle mode:
