Figure 4.3-5 Floating Decimal

Both scales are graduated with unequally spaced values printed from 10 to 90. The CR-3

uses a "floating decimal" (Figure 4.3-5) which allows the printed numbers to represent

different values, depending on where the decimal point or succeeding zero is placed. For

example, the number 21 may stand for .21, 2.1, 21, 210 or 2100. Not all numbers are

printed on the scales, therefore, the values will have to be read accurately between the

printed numbers.
