1. Formatting Numbers Writing Consultant Presentation EG 1003: Intro to Engineering and Design Polytechnic Institute of NYU

2. Use digits for numbers >10 The lab required the use of 16 paperclips and a space heater. Exception: A sentence cannot begin with a numeral Options: Spell out number is the first word of the sentence Rewrite the sentence so number is not first

3. Other <11 exceptions 1. Parts of a reportLab 1, Figure 2 2. Anything with a symbol: Percentages and ratios12%, 1:4 Measurements/currency12mm, $54 Times and datesOctober 12 3. Figures (numbers in tables, equations or diagram) 199520052015 545

4. Usually spell out ten or fewer The team ran 25 trials. There were eight teeth on the gear. The diameter was 3 cm, and materials cost $7. The due date is November 4. Thirty-five bricks were used. In the design, 35 bricks were used. The gear ratio was calculated as 3:1. Lab 7 will be presented today The front view is shown in Figure 2.

5. Round off to two decimal places Engineers are more practical than mathematicians Real-world measures are useful to the 100s, at best 10.33333333 10.33 10.1428571410.14 3.162277663.16

6. Use leading & trailing zeroes Use a zero before any decimal If some numbers have a decimal, all should.80.80 11.00.920.92

7. Software will line up decimals Try “decimal tab” to line up numbers: Use automatic rounding in Excel:

8.  Spell out numbers ten or fewer  Usually use digits when 11 or greater  Only two decimal places with leading and trailing zeroes  Exploit software features Formatting Numbers
