Usage
Basic Arithmetic:
2 + 2 * 2 = 6
(2 + 2) * 2 = 8
573/2 - 1221*6 = -7039.5
Power and Logarithms:
3 ^ 2 = 9 (3 to the 2nd power)
sqrt(9) = 3
9 ^ 0.5 = 3
log(2.7183) = 1.00000668491 (natural logarithm base-E)
log10(2.7183) = 0.434297385125 (logarithm base-10)
log10(100) = 2
Trigonometric Functions:
sin(90) = 1
arcsin(1) = 90 (you may also use asin instead of arcsin)
cos(60) = 0.5
arccos(0.5) = 60 <(you may also use acos instead of arccos)
tan(45) = 1
arctan(1) = 45 (you may also use atan instead of arctan)
Constants
