"It is total."
I'm guessing "totală" is the adjective, and would therefore match the gender of the noun it describes, so "total" with a masculine noun, "totală" with a feminine noun. This sentence doesn't mention the noun, but I assume in conversation, it would follow a sentence that referred to a feminine noun, hence "totală". However, there is also the noun "a total", which is neuter, so masculine when singular. This would produce "Un total" - a total, and "totalul" - the total.
