People who do well in maths have got good chances... but let's say you miss out on a finance job... then you're screwed. At least with accounting you can easily get into some crap like Big 4 auditing or you can even get into an investment bank doing auditing.
maths is a versatile and challenging degree to get . it's just difficult to compare the quality of degrees across different unis (the math schools vary quite a bit in size and strength). you could do a masters which i think would be good for programmer/analyst positions.
