# (indirection)

varNameString
#
Refers to the variable whose name is varNameString. This lets you
use strings to create variable names from within a function.
E
(scientific notation)
mantissa exponent
E
Enters a number in scientific notation. The number is interpreted as
exponent
mantissa × 10
.
Hint: If you want to enter a power of 10 without causing a decimal
value result, use 10^integer.
You can insert this operator from the computer keyboard by
Note:
typing @E. for example, type 2.3@E4 to enter 2.3

Matrix1 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
In Degree angle mode, multiplies Expr1 by g/100.
In Gradian mode, returns Expr1 unchanged.
You can insert this symbol from the computer keyboard by
Note:
typing @g.
R

Matrix1 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/
In Radian angle mode, returns the argument unchanged.
In Gradian mode, multiplies the argument by 200/
R
Hint: Use if you want to force radians in a function definition
regardless of the mode that prevails when the function is used.
