calc-rs's Issues

function solver tries to solve equations containing Riemann sums.

Description

If the solve_func function is passed a non-function equation with a Riemann Sum, then the function will attempt to solve it. This is a bug, it should report an error.

Example

cmd: cd rust-lib; echo '3(i=0_5$(i))' | cargo run
output: 3(i=0_5$(i)) => ("3(i", ([0, 1, 2, 3, 4, 5], [Some(0.0), Some(0.0), Some(0.0), Some(0.0), Some(0.0), Some(0.0)]))
expected: 3(i=0_5$(i)) => Some(45.0)
