Construction Calculator+++ vs SwiftRPN

Construction Calculator+++ helps you in construction math calculations. - Length-Width-Height Module: You can enter Length, Width, or Height values in Yard-Feet-Inch-Fractions, Decimal Feet, 
Decimal Inches, and Yards. Enter the Length and Width to calculate Area, Perimeter (of a room), and Square-up. In addition, enter the Height to calculate the Volume, Wall Area, and Total Room Area. You can enter any single length value and convert it to other dimensions, for example from Feet-Inch-Fractions to Decimal Feet or Decimal Inches or back. Furthermore you can tap on any calculated dimension to convert it to other dimensions. If the calculated value is Volume you can tap and see its conversion to Board Feet. - Bricks/Blocks/Pavers/Tiles Function calculates the number of Bricks/Blocks/Pavers/Tiles needed for a certain length or area. You can use the standard 8-inch x 16-inch size block/mortar (area of 128 square inches) or enter custom block size by height and length or area. Furthermore, this function allows you to quickly and simply add a waste allowance to the number of blocks calculated. - Drywall Sheets Function calculates the number of 4 x 8, 4 x 9, and 4 x 12 feet sheets required for an area or length. Furthermore, you can add your own custom size of Drywall Sheets. - Rafter Module: Enter any two of the four parameters, Rise, Run, Diagonal, or Pitch to calculate the unknowns. Run, Rise, and Diagonal values can be entered in Feet, Inches and Inch fractions or Decimal Feet and Decimal Inches. Pitch can be entered as a dimension in inches which is the amount of rise over 12 inches of run. Furthermore, Pitch can be entered as an angle in degrees, a percent grade or slope (pitch ratio). Tap on any of the values to see its conversion to other formats. In addition to Common Rafter, you can perform calculations of Regular and Irregular Hip/Valley and Jack Rafters. You can also calculate Plump and Level cut angles. Simply enter known values of Common Rafter and you are done. Length and cut angles of the adjoining Hip (or Valley) rafters, Incremental Jack Adjustment, Regular/Irregular Jack Rafter Lengths and Cut Angles for 16 Inch On Center Spacing are all automatically calculated. You can also enter an On Center Spacing other than 16 Inches. - Circle and Arc Module: Solves for parameters of circle and arc. The parameters include radius, diameter, area, circumference, arc length, arc angle, chord length (run), segment rise (rise), segment area, and pie slice area. A plot of circle or arc and its parameters is drawn to scale to visualize the parameters for you .

SwiftRPN is an RPN (Reverse Polish Notation) calculator that aims to be quick to open and easy to use. = RPN Stack Work quickly and efficiently using the RPN Stack by pushing and popping values. The stack will always show what series of inputs led to each output, so you won't lose context during complicated expressions. = Extended Types SwiftRPN can understand scalar types like integers and real numbers, as well as vectors and square matrices of sizes 2, 3, and 4. When operating purely in the scalar integer domain, SwiftRPN can promote up to BigInts to avoid floating point imprecision. = 80 Operators SwiftRPN has 84 built-in operators with included documentation and examples. All the expected operators (basic arithmetic, exponents, logarithms) are present, as are: - Rounding functions (floor/ceil/trunc/round) - Unit conversions - Bitwise operations (and/or/not/xor/shift left/shift right) - Statistics (avg/min/max/sum/std dev/NPV) - Trigonometry (sin/cos/tan + arc/hyperbolic variants) - Vector operations (dot/cross/normalize/length/swizzle) - Matrix operations (identity/inverse/transpose + translation/scale/rotation matrix generators) = Unit Conversions SwiftRPN has 74 built-in units, and can convert between units within families, including: - Angle - Area - Colors (3 and 4 components) - Coordinate systems (2D and 3D) - Length - Mass - Storage (Base 10 [SI, 1000 bytes in a kb] and Base 2 [1024 bytes in a kb]) - Temperature - Time - Volume = Value Representation SwiftRPN recognizes values represented in binary, octal, decimal, and hexidecimal. You can: - Enter values in one representation, and convert them to another - See the result of bitwise operations in binary automatically - View vec3 and vec4 components (truncated) in hexidecimal when working with colors.
