Rounding a decimal number means assigning it the value closest to the required precision. Depending on the level of rounding required, look at the figures immediately after:

  • if it is 0; 1; 2; 3 or 4 the rounded number remains unchanged
  • If it is 5; 6; 7; 8 or 9 the rounded number is increased by 1

Examples:
0.9273426 ➨ 0.927343 ; 0.91 ; 2.53 ; 1.34 ➨ 1.3
