Scientists may call it round number bias, for me as an engineer using dimensions that are divisible by 5 is simply a facet of “not getting frowned at by fitters and welders”. Especially in naval architecture, where tolerances are somewhere between 10 and 30. Millimeters.
As such I constantly find myself using the expression feature to set alternative rounding behaviors for my sliders, if you will.
x*5 for an offset value, x*50 or 100 for a height above base during initial design, etc. For this, an expression input would be most valuable.
