A.2.3. Exercise 3 solution

200 mod 7                                        -- 4
100 / 25 * 4                                     -- 16.0
((100.5 as integer) - (50.99 as integer) ) ^ 2   -- 2401.0
(1.234e+2 + 2.345e+3)                            -- 2468.4
2 ^ 0.5  -- this calculates the square root of 2 (1.414213562373)
(6 ^ 2 + 8 ^ 2) ^ 0.5                            -- 10.0
100.25 + 7.5 div 5 - 29 mod 8                    -- 96.25

A.2.4. Exercise 4 solution

log 5 * (100 - 32) / 9
log (100 as degrees Fahrenheit) as degrees Celsius

log 5 * (32 - 32) / 9
log (32 as degrees Fahrenheit) as degrees Celsius

log 5 * (0 - 32) / 9
log (0 as degrees Fahrenheit) as degrees Celsius

log 5 * (55 - 32) / 9
log (55 as degrees Fahrenheit) as degrees Celsius

A.2.5. Exercise 5 solution

(3.31E-8 + 2.01E-7) / (7.16E-6 + 2.01E-8)

A.2.6. Exercise 6 solution

log 365 + 7 - 365 mod 7
log 12258 + 23 - 12258 mod 23
log 996 + 4 - 996 mod 4

A.2.7. Exercise 7 solution
