## Number Sense

I saw in an equation today the value of .75.

For folks like me who wear bifocals and have little floating specks traversing our eyes, tiny little periods can easily be missed.

Therefore it is a good idea to express decimal values less than one with a zero before the decimal point.

Good Example:   0.75

See? It is so much clearer that this is a small number. And if this paper is going to be copied or faxed or scanned or digitized, having that zero present will solve any disappearing period issues and the end-user will know for a fact what the number is supposed to be.

Besides, the SPE Style Guide specifically says:
“When writing decimal fractions, place a zero to the left of the decimal point
(0.5 not .5).”

Numerical Typo of the Day:
2103′ instead of the year 2013

This is a two-fer boo-boo: not only is the number transposed, but the unit of measure is wrong, feet instead of a year. Note that you should use ft not ‘ to designate feet. Folks like me with bifocals and floaters can see “ft” a whole lot better than those tiny single quotation marks.
