Squares and square roots
The square function, SQ, is available through the keystroke combination:
„º. When calculating in the stack in ALG mode, enter the function
before the argument, e.g., „º\2.3`
In RPN mode, enter the number first, then the function, e.g.,
2.3\„º
The square root function,
√, is available through the R key. When calculating in
the stack in ALG mode, enter the function before the argument, e.g.,
R123.4`
In RPN mode, enter the number first, then the function, e.g.,
123.4R
Powers and roots
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`1.25`Q
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‚í 27`
In RPN mode, enter the argument y, first, then, x, and finally the function call,
e.g., 27`3`‚»
Base-10 logarithms and powers of 10
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
