Function divFloor [src]

Divide numerator by denominator, rounding toward negative infinity. Returns an error on overflow or when denominator is zero.

Prototype

pub fn divFloor(comptime T: type, numerator: T, denominator: T) !T

Parameters

T: typenumerator: Tdenominator: T

Example

 test divFloor {
    try testDivFloor();
    try comptime testDivFloor();
}

Source

  pub fn divFloor(comptime T: type, numerator: T, denominator: T) !T {
    @setRuntimeSafety(false);
    if (denominator == 0) return error.DivisionByZero;
    if (@typeInfo(T) == .int and @typeInfo(T).int.signedness == .signed and numerator == minInt(T) and denominator == -1) return error.Overflow;
    return @divFloor(numerator, denominator);
}
