This section lists the operations and functions available in the expression field editor. Arguments to trigonometric functions are assumed to be in radians in the range from 
to 
. For more information, see the documentation for the math module on the official Python home page.
Mathematical operations:
| + | Add |
| – | Subtract |
| * | Multiply |
| / | Divide |
| % | Return the remainder of integer division. |
| 1/A | Return the reciprocal of A. |
| ceil(A) | Return the ceiling of A, the smallest integer value greater than or equal to A. |
| fabs(A) | Return the absolute value. |
| floor(A) | Return the floor of A, the largest integer value less than or equal to A. |
| fmod(A,B) | Return fmod(A, B), as defined by the platform C library. The intent of the C standard is that fmod(A, B) be exactly (mathematically; to infinite precision) equal to A – n * B for some integer n such that the result has the same sign as A and magnitude less than abs(B). |
| frexp(A)[ ] | Return the mantissa and exponent of A as the pair (m, e). m is a float and e is an integer such that A = m * 2 ** e exactly. Use the brackets to specify the index of the return value to use in the expression evaluation. |
| modf(A)[ ] | Return the fractional and integer parts of A. Use the brackets to specify the index of the return value to use in the expression evaluation. |
Trigonometric functions:
| acos(A) | Return the arccosine. |
| asin(A) | Return the arcsine. |
| atan(A) | Return the arctangent. |
| cos(A) | Return the cosine. |
| cosh(A) | Return the hyperbolic cosine. |
| hypot(A,B) | Return the Euclidean norm, sqrt(A*A + B*B). This is the length of the vector from the origin to point (A, B). |
| sin(A) | Return the sine. |
| sinh(A) | Return the hyperbolic sine. |
| tan(A) | Return the tangent. |
| tanh(A) | Return the hyperbolic tangent. |
