Floor Function

The floor function is one of the commonly used mathematical functions in quantitative trading, used to round down a number to the nearest integer.

Calculation Principle

The floor function is calculated using the following formula:

y = floor(x)

Where:

  • x: Input value (range: -∞ to +∞)
  • y: The largest integer less than or equal to x

Parameter Description

  • Input Parameters: One K-line data series
  • Output: Series of rounded-down integers

Usage Recommendations

  1. Pay attention to input value range
  2. Consider numerical precision
  3. Pay attention to result interpretation
  4. Consider rounding characteristics
  5. Pay attention to boundary value handling
  6. Consider practical application scenarios

Notes

  • Ensure data quality
  • Pay attention to data preprocessing
  • Consider the impact of extreme values
  • Pay attention to numerical range
  • Consider result stability
  • Pay attention to computational efficiency
  • Pay attention to practical application scenarios
  • Pay attention to boundary value handling
  • Consider result interpretation
