I have a form with two fields for numeric values and a third field that is populated by the Form > Properties > Calculations function. The calculation I've entered into the form properties is:

whratio = {waist:value}/{hips:value}

If waist:value and hips:value are integers, then whratio is calculated correctly.

Example:
waist = 34
hip = 36
whratio = 0.93 correct!

However, if the number of decimal places is more than zero, strange behaviours result:

Example:
waist = 34
hip = 36.5
whratio = 9.32 ????

Example:
waist = 34.0
hip = 36.5
whratio = 0.93 correct!

Example
waist = 34
hip = 36.50
whratio = 0.93 !!!!

Can anyone offer any insight into this weirdness? I originally thought there might be JavaScript errors elsewhere in my Form Properties but this set-up is using RSform Pro's own Calculations facility and not any of my other calculations' JavaScript.

Is this a bug in the core RSform calculation processor or do I need to add something else to my calculation definition? Does JavaScript work there? Or PHP? Any clues would be greatly appreciated.

UPDATE:
On the advice of RSjoomla Tech Support, I re-downloaded and re-installed RSform Pro with (apparently) a fix for this issue installed. Problem SOLVED
