Display style of length units
Display style of length units is defined by format, precision and unit symbol.
Format
The format can be:
-
scientific (1.55E+01)
-
engineering (15.50E+00) (the exponent is ..., -09, -06, -03, +00, +03, +06, +09, ... )
-
decimal (15.50)
-
fractional (15 1/2)
Precision
The precision for scientific and decimal format is defined as follows. Sample value is 3.1415926

Input of length units
For metric units (mm, cm, dm, m), the scientific and decimal formats are supported. Once the value is input, the value is transformed into the defined format, precision and unit.
For the imperial units (in and ft), the scientific, decimal and fractional formats are supported. The use of symbols " and ' is supported. The fractional input (-1/2, -3/4, …) is supported. When entering fractions, the fractions must be separated from the rest by a hyphen. Once the value is input, the value is transformed into the defined format (scientific, decimal, fractional), precision and unit symbol.
It is always possible to enter a number in greater precision than defined by settings. The precise value is stored internally and the displayed value reflects the Units setup.
