0 string precision and a sequence expression. Clever.

let's say you have an upper bound on the length of the "=" sequence
(in my example it is 60)

# 123456789+123456789+123456789+123456789+123456789+123456789+
# 1 2 3 4 5 6
a="============================================================"
n=20
echo ${a::$n}
