1 BASIC OPERATIONS

1.1 Accumulator Operations (see Chapter 3)

'x' represents a floating point number held in 509.0.

Similarly, y = (510), z = (511).

Exercises

1. Place x in store line 500.0, y in 501.0, and z in 502.0
2. Place -x in store line 500.0, and clear (i.e. set to zero) store lines 509.0 and 510.0.
3. Replace x by y, y by -z, and z by x
4. Calculate (2x - y) and leave the result in Am
5. Put (17x - 12y) into line 512
6. Replace x by xy, y by yz, and z by zx
7. Write (x² + y² + z²) to line 500 and (x² - y² + z²) to line 501
8. Compute (x - y)⁵ and write the result to line 512
9. Leave in the accumulator the quantity -(x - y) (y - z) (z - x)
10. Replace x by y/z, y by z/x and z by x/y
11. Compute (x-y)/(y-z) and place the quotient in line 40
12. Evaluate -(x-y)(y-z)(z-x) / (x² + y² + z²) and leave the result in the accumulator
13. Write sqrt(x/y) in place of z

1.2 B-register operations (see Chapter 4)

Exercises

'a' represents the contents of half word 510.4. Similarly, b = (511.0), c = (511.4).

1. Place a in B1, b in B2 and c in B3
2. Place a in store line 512.0, b in 512.4, and c in 513.0
3. Place 2b in B1, 3b in B2, and 7b in B3
4. Replace a by (a + b + c)
5. Replace b by (a - b + c)
6. Replace a by -b, b by -c, and c by -a
7. Calculate [4(a + b) - 3c] and leave the result in B20
8. Write 11.4 to B1, (11.4) to B2 and -25 to B3

1.3 Common extracode operations (see Chapter 7)

Exercises

Suppose x = (10), y = (11), z = (12) are floating point numbers. Store any constants required. Place in store line 13 of each of the following.

1. |x| -|y| (Better done with 367)
2. z tan x
3. Arctan (1 + integral part of x²)
4. (x² + y²)^-z
