I failed Maths for Computer Science in my degree but managed to get a pass on it as all my other grades were great. Overall it has really not affected my life in any way or my career throughout my 15 years as a code monkey through many roles into now a CTO position for the past 5.
There are a lot of things and patterns you pick up as you go, and maybe I just got lucky and was in the sweet spot of tools developing fast enough to act like a permanent crutch for lack of mathematic ability.
I guess this is different if I were planning to be a game programmer but for a web focused engineer it has been absolutely fine
