Question:
What is the standard way of writing algebraic functions (square roots, X to
the power of, etc.) in standard DOS text?
Replies:
Operating systems (like DOS) generally do not support any math functions
more complex than +, , *, and /. It's programming languages where you
find powers, exponentiation, and roots; and the notation varies from
language to language. FORTRAN uses "**" as in x=y**z; C uses a power
function as in x=power(y,z). Roots are, of course, just fractional
powers, but most languages use "SQRT" for squareroot as in x=SQRT(y)
because the squareroot function is the most commonly used root.
The particular case of "e" to a power is usually denoted x=EXP(y).
In ASCII text you usually see "**" or "^" to denote powers, as in:
x=y**z or x=y^z.
