@Thevy29 Great Britain Pound (£)

@SomeMichGuy Man, you guys are behind the times, we stopped using Pounds like back in the 60's.

@Thevy29 Are you referring to the pre-decimal pound?

@SomeMichGuy @Thevy29 Enough silliness. Now, please suggest.

@SomeMichGuy Not sure, it was phased out to dollars here is Australia, way before I was born. But the older generation still complain about it.

@Thevy29 Oh, AUSTRALIA

"GBP" is the ISO currency code for the British pound (the "pound Sterling").

The pound was set up as recorded at

https://en.m.wikipedia.org/wiki/%C2%A3sd

on the £sd (pound shilling pence, "The abbreviation originates from the Latin currency denominations librae, solidi, and denarii.[1] ").

There were
4 farthings in 1 penny
12 pence in 1 shilling
20 shillings in 1 £ (= 240 pence)
21 shillings in 1 guinea (= 252 pence)

This might seem odd, but having a large number of factors of the number of (in this case) pence per £ makes it easier for people to figure out various fractions of a number.

240 = 24 * 10 = (3 * 8) * (2 * 5)
= 3 * (2^3) * 2 * 5
= 2^4 * 3 * 5

This means that, in pence, you can quickly figure these fractions:

1/2
1/3
1/4
1/5
1/6

1/8

1/10

1/12

1/15

1/16

1/24
...
1/240

Guineas extend this further.

@SomeMichGuy That's a lot of maths, and strangely the Japs make more computers then you guys...

@Thevy29 It's basic math--find the factors of a number (240, in the example), then make a sequence of the numbers you can create from that)...

Ordinary people using the pound-shilling-pence system did that.

Lots of factors = easy to divide a number EXACTLY

For instance, you can quickly get thirds in that system. In the decimal system, there is no 3 built into the factors of 10.
