  // normal is abandoned,recommended to use floor
  formatFloor(2.0810, 2, 'normal') // 2.08

  formatFloor(2.0810, 2, 'floor') // 2.08
  
  // normal is abandoned,recommended to use floor
  formatFloor(2.0810, 1, 'normal') // 2

  formatFloor(2.0810, 1) // 2.1
  formatFloor(2.2810, 2, 'round) // 2.28
  formatFloor(2.2850, 2, 'round) // 2.29
  formatFloor(2.2950, 2, 'round) // 2.3

  formatFloor(0.1050, 2, 'ceil', {
    unit: '￥'
  }) // 0.11￥

Updated

  Remove the format candidate value normal of the formatFloor function.But it will not affect the original normal formatting. The best solution is to use floor instead of the original normal.

  Example:

  formatFloor(2.0810, 2, 'normal')
  // the same as
  formatFloor(2.0810, 2, 'floor')
  
  Now, the formatFloor function increases the use of round, its purpose is to round the value.

  Example:

  formatFloor(2.0850, 2, 'round') // 2.09
