Syntax: calc [formula]> A calculator that lets you do integer or floating point calculations. You may specify a floating point (real) number by ensuring you write the decimal point followed by at least one digit. Generally functions and operators return the same type argument as they are passed; if arguments are mixed real numbers are returned. Operators: +, -, *, /, %, ^ Functions: abs(a) - Absolute value (if complex number answer will be float) arg(a) - Argument of a complex number. Returns float. complex(a, b) - Returns a+bi cos(radians) - returns cosine of angle div(a, b) - integer division ( a/b does floating point) exp(x) - returns e^x float(a) - Converts a to a float with to_float efun int(a) - Rounds a to nearest integer ln(x) - returns natural logarithm of x polar(abs, arg) - Returns complex number given polar coordinates sin(radians) - returns sine of angle sqrt(positive_int) - square root of positive integer as a float tan(radians) - returns tangent of angle to_int(a) - Converts a to an integer using to_int efun Constants: e = 2.718282 i = 0+1i pi = 3.141593 Example: calc (2+-1)*-sin(1) calc polar(abs(3+2i), arg(3+2i))
