Webel: Mathematica: CONVENTION: A '$Q$' in a function variant name indicates that it is a variant where every argument is strictly either a Quantity or dimensionless Real. Compare with '$SI$' functions.

Webel IT Australia promotes the amazing Mathematica tool and the powerful Wolfram Language and offers professional Mathematica services for computational computing and data analysis. Our Mathematica tips, issue tracking, and wishlist is offered here most constructively to help improve the tool and language and support the Mathematica user community.

Note that whilst a "symbolic" '$E$' function can accept Quantities, a '$Q$' function may only accept Quantity or dimensionless Real arguments. For an example visit this slide:

Note also that a '$Q$' function can't be directly compiled to a '$C$' function variant. Visit also:
Webel: Mathematica: CONVENTION: An '$SI$' in a function variant name indicates that all arguments are SI Real convention (no Quantity arguments with units). An '$SI$' function can also be used to generate '$C$' compiled function variants.
Webel: Mathematica: CONVENTION: An '$E$' in a function name indicates that it is symbolic (takes Blank expression arguments). An '$E$' function can also be used with Quantity inputs and can be used to generate '$C$' compiled function variants.
Webel: Mathematica: CONVENTION: A '$C$' in a function name indicates that it is a compiled variant. Typically it is compiled from an '$E$' symbolic function or an '$SI$' Real convention function.
