EPS equals 0 problem for single precision

[alanwilliams1]

Hi there,

When I run the tests and examples for single precision, they all fail because EPS is evaluated to zero. I've changed the code manually so that EPS = 5E-8 and it runs correctly.

The double precision tests and examples run fine.

Does anyone know why EPS might be evaluating to zero in the single precision case?

Thanks!
Alan
