Traits

• Average
  Provides methods to compute the average of two integers, without overflows.
• Integer
• Roots
  Provides methods to compute an integer’s square root, cube root, and arbitrary nth root.

Functions

• average_ceil
  Returns the ceiling value of the average of x and y – see Average::average_ceil.
• average_floor
  Returns the floor value of the average of x and y – see Average::average_floor.
• binomial
  Calculate the binomial coefficient.
• cbrt
  Returns the truncated principal cube root of an integer – see Roots::cbrt.
• div_ceil
  Ceiled integer division
• div_floor
  Floored integer division
• div_mod_floor
  Simultaneous floored integer division and modulus
• div_rem
  Simultaneous integer division and modulus
• gcd
  Calculates the Greatest Common Divisor (GCD) of the number and other. The result is always non-negative.
• gcd_lcm
  Calculates the Greatest Common Divisor (GCD) and Lowest Common Multiple (LCM) of the number and other.
• lcm
  Calculates the Lowest Common Multiple (LCM) of the number and other.
• mod_floor
  Floored integer modulus
• multinomial
  Calculate the multinomial coefficient.
• multiply_and_divide 🔒
  Calculate r * a / b, avoiding overflows and fractions.
• nth_root
  Returns the truncated principal nth root of an integer – see Roots::nth_root.
• sqrt
  Returns the truncated principal square root of an integer – see Roots::sqrt.
