JAG Field Calculators  (JFC) W10
Understanding (JFC)
JFC allows you to create and maintain a collection of field calculators that you can use to quickly calculate special items specific to the construction industry like the number trucks required to support an excavation or concrete pour as well as other more common items like the volume and surface area of a sphere or circular slab. You can pin individual Calculators to your Windows 10 Start screen. You can also text or email the Calculator Output and Input Parameter values. This comes in handy when ordering concrete when you're in the field. JFC uses pictograms to convey calculator input parameter context. Each calculator preserves your Input Parameters and Output Results which you can then edit and change at any time.
