Add a script benchmark

@@ -135,6 +135,10 @@ Because this `bc` packs more than `1` decimal digit per hardware integer, this
 `bc` is faster than GNU `bc` and can be *much* faster. Full benchmarks can be
 found at [manuals/benchmarks.md][19].
 
+There is one instance where this `bc` is slower: if scripts are light on math.
+This is because this `bc`'s intepreter is slightly slower than GNU `bc`, but
+that is because it is more robust. See the [benchmarks][19].

 ## Algorithms
 
 To see what algorithms this `bc` uses, see the [algorithms manual][7].

+### Scripts
+
+A script was created that contained the following:
+
+```
+#!/bin/sh
+
+exe="$1"
+
+for i in $(seq 0 1000); do
+	printf '%d\n' "$i" | "$exe" -q tests/bc/scripts/timeconst.bc > /dev/null
+done
+```
+
+where `tests/bc/scripts/timeconst.bc` is [this file][1]. The script was saved at
+`../test.sh`.
+
+The command used was:
+
+```
+time -p sh ../test.sh [bc]
