Subject: Number Conventions Hello Everyone,
Some employees are not using our number conventions. Please review these guidelines for ensuring consistency and accuracy.
Double-check your exponents. Someone recently recorded a quantity as cubed instead of squared. This caused serious errors in the results of the project.
Very large and small quantities are easy to misread in decimal form. Express them in scientific notation. Raising a figure to the nth power is more reliable.
Use appropriate significant figures. This prevents problems from rounding errors. Most of our formulas require precision to the thousandths. Rounding to tenths or hundredths instead produces inaccurate results. Use trailing zeros to indicate your number of significant figures.
Thanks for your cooperation.
