In AutoCAD table cells and text fields (texts, block attributes) you can use not only the predefined properties, fields and functions but also the standard mathematic (arithmetic and goniometric) functions with dynamic values.
When defining the arithmetic expressions  see Fields > All > Expression  you can use the following functions:
 +, , *, /, ^, () = basic arithmetic operations
 sin(angle) = Sinus of an angle
 cos(angle) = Cosinus of an angle
 tang(angle) = Tangens of an angle
 asin(real) = Arcus sinus
 acos(real) = Arcus cosinus
 atan(real) = Arcus tangens
 ln(real) = Natural logarithm
 log(real) = Decimal logarithm
 exp(real) = Natural power
 exp10(real) = Decimal power
 sqr(real) = Square
 sqrt(real) = Square root
 abs(real) = Absolute value
 round(real) = Rounded to the nearest integer
 trunc(real) = Truncated to integer
 r2d(angle) = Angle in radians converted to degrees
 d2r(angle) = Angle in degrees converted to radians
 pi = Pi constant (Ludolf's number)
Example: =atan(pi)
Rightclick in the Expression panel of the FIELD dialog and use Insert field... to nest (combine) field expressions and add, subtract, muliply, divide, etc. multiple fields. So you can e.g. multiply the area of the selected closed polyline and its thickness to get the dynamic value of its volume (rtclick, Insert field, object property Area * rtclick, Insert field, object property Thickness). Use "(none)" for formatting the numeric fields.
