CONSTANTS

CONSTANTS(g) or C(g) provides the value of various constants, according to the contents of g: e (for a string of 'e' or 'E'), π ('pi' or 'PI'), missing value ('*'), the conversion factor by which to multiply radians to get degrees ('degrees'), the conversion factor by which to multiply degrees to get radians ('radians') and the number ε defined as the smallest number such that the calculation 1+ε is detectable on the computer as greater than one ('epsilon').
