Workers Fraction Calculator app for iPhone and iPad

=== What is it? ===

Workers Fraction Calculator (WFC) and Workers Fraction Calculator Pro (WFC Pro) is a mobile calculator app optimized for fraction math—both pure (unit-less) fractional expressions and length measurements (feet, inches, meters, centimeters, miles, nanometers, etc.)

=== Features, features, features! ===

- NO ads.

- Reduces fractions to lowest form.
- Build complete input expression before calculating result.
- Decimal in Words display (e.g. 42 = Forty-Two).
- Standard order of operations used to calculate expression (aka PEDMAS / BEDMAS).
- Rounding mode with fractional precision options (to nearest 1/4, 1/8, etc. of choice).
- Rounded result also displayed with nearest greater-than and nearest lower-than values.
- Fraction rounding with remainder in alternate units (Example: Round 27/64 inch to nearest 32nd. Result = 13/32 inch Remainder 15.62 thou).
- Mix feet, inches, metres, other unit in one expression and get result in unit of choice.

- Built-in step-by-step tutorial system.

= Calculation Examples =

Pure Fractions:
1/3 + 4/5 = 1 and 2/15

Length Measurement:
5 ft 7 and 3/4 in + 3 and 5/8 in = 5 ft 11 and 3/8 in (rounded to nearest 1/8th in)

Complex Expression:
(2500 mm + 2 ft 4 and 3/8 in + 78.5 in) ÷ 2 = 8 ft 6 and 5/8 in (rounded to nearest 1/8th in)
(Description: Add millimeters + feet-and-inches + inches for total length, then divide by 2 to find the midpoint)


= Unit Conversion for Calculation Example: =
5 ft 7 and 3/4 in + 3 and 5/8 in = 5 ft 11 and 3/8 in (rounded to nearest 1/8th in)
