which separates the whole number and the decimal part of that number. For this purpose,
the decimal point is used. Therefore, 1.564 is written as

Dots 4, 6 indicate structural shape modifiers too. What do you mean by a structural
modifier? See the literary meaning. Suppose, take a triangle, where all the three sides are
equal. By making some modifications in the sides of the triangle, we can get a scalene
triangle, isosceles triangle and right angle triangle. The logic here is that you indicate the
triangle first and then indicate that the triangle is scalene in nature. Therefore, the code
for triangle followed by the code for modification will indicate the modified triangle. You
will learn more about this in the section dealing with shape indicator.

Dots 4 and 6 followed by the alphabets indicate the Greek letters. In mathematics and
science textbooks, Greek letters such as alpha, beta, gamma, delta, etc., are used. In most
of the cases, the first letter of the Greek letter is indicated by the first letter of the
equivalent English alphabet preceded by dots 4 and 6. However, the use of first letters
may not be correct in the case of some Greek letters. See how the Greek letters are
indicated below:

Alpha - α Gamma - γ

Beta - β iota - ι

Delta - δ Kapta - κ

Epsilon - ε Lambda - λ

Phi - φ Mu - μ
