Example:
eval(2+3) returns 5
evalc
Returns a complex expression written in the form real+i*imag.
evalc(Expr)
Example:
evalc returns
evalf
Given an expression and a number of signicant digits, returns the numerical evaluation of the expression to
the given number of signicant digits. With just an expression, returns the numerical evaluation based on the
CAS settings.
evalf(Expr,[Integer])
Example:
evalf(2/3) gives 0.666666666667
even
Tests whether or not an integer is even. Returns 1 if it is and 0 if it is not.
Example:
even(1251) returns 0
exact
