Methods

`Static`addExact

addExact(x: number, y: number): number
Returns the sum of the two arguments; throwing an exception if the result overflows a long integer.
Parameters
- x: number
  The first value
- y: number
  The second value
Returns number
The result of adding the two values

Throws
ArithmeticError if the result overflows a long integer
- Defined in solo/solo/src/core/util/math_ex.ts:39

`Static`floorDiv

floorDiv(x: number, y: number): number
Returns the floor division of the two arguments; throwing an exception if the result overflows a long integer.
Parameters
- x: number
  The dividend
- y: number
  The divisor
Returns number
The quotient of dividing the two values rounded towards positive infinity.

`Static`floorMod

floorMod(x: number, y: number): number
Returns the remainder of the floor division of the two arguments; throwing an exception if the result overflows a long integer.
Parameters
- x: number
  The dividend
- y: number
  The divisor
Returns number
The remainder of dividing the two values rounded towards positive infinity.
