• The power function, ^, is available through the Q key. When
calculating in the stack in ALG mode, enter the base (y) followed by the
Q key, and then the exponent (x), e.g.,
5.2Q1.25`
In RPN mode, enter the number first, then the function, e.g.,
5.2`1.25Q
• The root function, XROOT(y,x), is available through the keystroke
combination ‚». When calculating in the stack in ALG mode,
enter the function XROOT followed by the arguments (y,x), separated
by commas, e.g.,
‚»3‚í27`
In RPN mode, enter the argument y, first, then, x, and finally the
function call, e.g.,
27`3‚»
• Logarithms of base 10 are calculated by the keystroke combination
‚Ã (function LOG) while its inverse function (ALOG, or
antilogarithm) is calculated by using „Â. In ALG mode, the
function is entered before the argument:
‚Ã2.45`
„Â\2.3`
In RPN mode, the argument is entered before the function
2.45‚Ã
2.3\„Â
Using powers of 10 in entering data
Powers of ten, i.e., numbers of the form -4.5 ×10
-2
, etc., are entered by
using the
V key. For example, in ALG mode:
\4.5V\2`
Or, in RPN mode:
4.5\V2\`
• Natural logarithms are calculated by using ‚¹ (function LN) while
the exponential function (EXP) is calculated by using „¸. In ALG
mode, the function is entered before the argument:
‚¹2.45`
„¸\2.3`
In RPN mode, the argument is entered before the function
