Theme: the numeral and the pronoun

Dates

The word day is not normally included with the ordinal number identifying it,
and the specification of the date is generally as exact as is required in the context.
Hence, no year is mentioned in 1, and the century is unspecified in 4.
1 Any time between June and July the ninth <9 July> then, (CONV)
2 On the fourth of July two thousand and nineteen <4 July, 2019>
(CONV)
3 In nineteen seventy-nine <1979> an unusual -phenomenon happened.
(CONV)
4 A: You ex deserted in October didn't you?
B: October thirty-two . (CONV)
C. Currency
Often the words for the currency units (pounds, pence/p; dollars, cents) are
omitted as predictable. This is especially so when sums of money involving two
sizes of unit are being specified: both are absent in 2, 4, and one in 1. Contrast
example 3.
1 You can have one player and it costs forty-four pound ninety-nine
<£44.99>. (BrE CONVJ)
2 A: It's three ten <£3.10> isn't it, didn't you say?
B: Three fifty <£3.50>. (BrE CONV)
3 And they can be yours for just one hundred and forty nine dollars.
<$149.00> (AmE CONV)
4 I told him I wanted five fifty <$5.50> an hour. (AmE CONV)
The singular form pound in 1 is colloquial; pounds would normally be considered
standard. Compare also the expression in example 3 in E below.
D. Temperature
Again the words for units and scales of temperature may be absent, when the speaker feels this information is shared already with the hearer—wholly in example 1, partly in 2.
1 The erm wind chill factor is twenty-two <22°> below. (coNvf)
2 It's ten degrees - ten above zero <10°>. (coNvf)
3 The Three Hundred Club is for people who have a, done a South Pole Streak from sauna, two thousand, oh two hundred degrees fahrenheit
<2000 .. . 200° F> to outdoors minus one hundred degrees fahrenheit <-100°F>. (CONVJ)
4 So it's twenty-five degrees Celsius <25° C> in January? (CONV) Types of phrase 11 1
E. Decimals, percentages, fractions
Decimals after the point are spoken as a sequence of digits, not a whole number.
For example, one will not typically hem four point thirty—cf. 4 and examples in F.
Example 3 is special in that the reference is to a sum of money.
1 Point five <.5> of a quart is a pint, (coNvi)
2 It's nought point five <0.5>. (CONV)
3 He's got this other stuff in there, some promotional special offer one point seventy-nine <£1.79> for a litre. (coNvf)

5 David Jones the chief economist of Nat West Bank expects output to rise by only point six percent <.6%> this year, (CONV)
6 Then it's going down another <.. .> three quarters of a percent <% %>. (cONVf)
F. Mathematical expressions
These may include words for arithmetic operations such as and/plus/add for addition, minus/take away/subtract for subtraction, times/multiplied by for multiplication, over/divided by for division and is, lmakes/equals for equation.
Twenty-two point two eight plus twenty point four eight minus forty-seven point six eight <22.28 + 20.48 - 47.68>. (co Nvt)
Fifteen add fifteen is thirty add one is thirty-one <15 + 15 = 30; 30 + 1 = 31>. (BrE coNvf)
Mine's twelve plus tip, so I'm going to put in fourteen. <$12 + $2 tip = $14> (AmE CONV)
Two point nine eight times four to the power of two <(2.98 x 42) or (2.98 x 4) 2 >. (coNvf)
V equals point two five eight cubed . (CONV)
Approximate numbers
Where it is not possible to specify an exact number, an alternative is to use a round number, such as 10, 30, 500 (note the higher frequency of round numbers, 2.4.13.3). Other options are provided by quantifying nouns (4.3.6) and determiners (4.4.4). In addition, there are various ways of qualifying exact numbers.
