Difference between get_discount_total() and get_total_discount()?

Question

In WooCommerce, I notice in both WC_Cart and WC_Order, there's both get_total_discount() and get_discount_total().

What is the difference between these? Which should I use to get the value of the discount on a cart/order?

Answer 1

Funny. I didn't notice it before.

get_total_discount will return a formatted value of the discount (with the currency symbol, wrapped with HTML).

get_discount_total will return just the value.
