LANGUAGE : LARGE ANDSMALL NUMBERS
For decimal values, we say “point” for the
decimal points and pronounce the next numbers
individually. We don’t always mention the 0 to
the left of the decimal point for values ;less than
1
Example : 0,56 ( nought point five six )
To express large and small numbers, we often
use prefixes. For example, kilo-means 1,000. the
main stress is on the first syllable of the prefix
Example : A 3,6-killobyte file
