Yes, most computer science majors want at least one calculus course.

The language of the computer is mathematics and the language of mathematics is not English. Mathematics includes a rich system of symbols that has been perfected over time to be able to represent all kinds of concepts that might arise in a field as dynamic as computers and computing today. We can’t explore what each one means or do mathematical calculations without it! Calculus lays out many concepts for us to use which will speed up our work significantly.”

Calculus helps solve those types of problems where it’s difficult for finite-precision arithmetic (the numeric approximation methods we’ve traditionally used) because there are so many places where small errors would accumulate wildly or lead to overflow errors – situations.
