This operator returns -value1 if value1 < 0 and value1 if value1 > 0
num1 num2 add num3
This operator returns the sum of the two arguments.
This operator returns the arctangent of the ration numerator/denominator.
This operator returns the smallest integer greater than value1
This operator returns the cosine of value1, where value1 is an angle expressed in degrees.
num1 num2 div num3
This operator returns the result of dividing num1 by num2. The result is always a real.
This operator returns the value of base raised to the exponent power.
This operator returns the greatest integer less than value1
This operator returns the natural logarithm of value1.
This operator returns the base 10 logarithm of value1.
This operator multiplies the first two operands on the stack and pushes the result back onto the stack. The result is an integer if both operands are integers and the product is not out of range. If the product is too big, or one of the operands is a real, the result will be a real.
This operator returns -value1.
This operator returns the nearest integer to value1, or the nearest, largest integer in the case of a tie.
This operator returns the sine of value1, where value1 is an angle expressed in degrees.
This operator returns the square root of value1.
num1 num2 sub num3
This operator returns the result of subtracting num2 from num1.
This operator returns value1 without its fractional part. Thus 4.3 becomes 4, -3.8 becomes -3.
