Description

Convert a construction measurement in US Customary Units (foot + inch) with or without a fraction into its equivalent as an Engineering value (LibreCAD style)

Usage

construction_decimal_eng(measurement)

Arguments

measurement

character or numeric vector that contains the construction measurement (decimal or foot + inch)

Value

the engineering construction measurement value as a character vector. In LibreCAD, a construction measurement of 1'-2 7/16" = 14.43112 (decimal) = 1'-2.43112" (engineering).
