Syntax
SUM FROM symbol = expression TO expression { expression }
Implemented in iMath since version 2.2.0 or earlier.
Explanation
Create a sum function summing up the expression in curly brackets from the lower bound to the upper bound. The function can then be symbolically evaluated with SIMPLIFY.
Example
EQDEF S = SUM FROM x = 1 to 100 {x}
EQDEF SIMPLIFY(@prev@ , "sum")
This will calculate the value of S as 5050.
