Decimal Child 

When your family has an even number of children and there is not an exact middle child, the “middle children” are called decimal children. This is because there is no even number with a whole number as the exact middle. The middle of 4 is 2.5.
That family with 4 children has 2 decimal children. The “middle children”.

decimal fraction 

Used in a minority of countries to pretend the presence of a metric system, when in fact a non-metric system is used. Instead of using a designated smaller unit or real fraction, the bigger unit is used with a decimal point.

More often used in combination with the decimal system to describe numbers that are not even.
Geoff: “It’m 6 feet and 5 inches tall.”

Heidi: “uh… I only know the metric system.”

Geoff: “Oh, sorry. That’s 6 5/12 feet.”

Heidi: “That’s a real fraction, not metric, though.”

Geoff: “Oh right. I mean 6.42 feet.”

Heidi: “OK, that’s a decimal fraction alright, but still not metric 🤣”
Geoff: “Hey Siri, what’s 6 feet and 5 inches in metric?”
Siri: “6 feet, 5 inches is equivalent to about 1.96 meters.”

In sales terms, a whale is a prospect that is significantly larger than an organization’s average customer.

Whales are large and extremely difficult to close. Due to their immense size, they are highly sought-after.

A whale is typically identified at first by a whale hunter on the sales team, but often requires cross-discipline participation in order to close; this includes assistance from operations, engineering, creative, client success, and business development teams.
"Shit...the sales director chewed me out on the sales call this morning. He's totally pissed that I have nothing in my pipeline. I've been focused on this one whale for so long that I haven't had time to prospect for normal-sized deals."
