  1. SINGLE ROW FUNCTIONS 1. NUMBERS MANIPULATION Prof. Carmen Popescu Oracle Academy Lead Adjunct

  2. ABS • ABS(n) • returns the absolute value of n • ABS(10) = 10 • ABS(-5.8) = 5.8

  3. CEIL, FLOOR • Ceil(nr) • FLOOR(nr) CEIL returns the smallest integer that is greater or equal to nr FLOOR returns the largest integer that is smaller or equal to nr

  4. CEIL, FLOOR Example • CEIL(nr) • CEIL(2) = 2 • CEIL(1.3) = 2 • CEIL(1.8) = 2 • CEIL(-2.3) = -2 • FLOOR(nr) • FLOOR(2) = 2 • FLOOR(1.3) = 1 • FLOOR(1.8) = 1 • FLOOR(-2.3) = -3

  5. MOD • MOD(n1,n2) MOD divides n1 by n2 and tells the remainder • MOD(100,10) = 0 • MOD(22,23) = 22 • MOD(-30.23,7) = -2.23 • 7*(-4) + (–2.23) = - 30.23 • MOD(4.1,0.3) = 0.2 • 0.3* 13 + 0.2 = 4.1

  6. POWER • POWER(n1,n2) • POWER(3,2) = 9 • POWER(3,3) = 27 • POWER(3,1.086)=3.29726371 • POWER(64,0.5) = 8

  7. ROUND • ROUND(value,precision) • ROUND(55.5) = 56 • ROUND(33.3) = 33 • ROUND(-55.5) = -56 • ROUND(-33.3) = -33 • ROUND(45.926,2) = 45.93 • ROUND(45.923,2) = 45.92 • ROUND(45.926,-1) = 50 • ROUND(42.926,-1) = 40 • ROUND(45.926,-2) = 0 • ROUND(65.926,-2) = 100

  8. TRUNC • TRUNC(value,precision) • TRUNC(55.5) = 55 • TRUNC(33.3) = 33 • TRUNC(-55.5) = -55 • TRUNC(-33.3) = -33 • TRUNC(45.926,2) = 45.92 • TRUNC(45.923,2) = 45.92 • TRUNC(45.926,-1) = 50 • TRUNC(42.926,-1) = 40 • TRUNC(45.926,-2) = 0 • TRUNC(65.926,-2) = 0
