# Function smallerEq Test whether value x is smaller or equal to y. The function returns true when x is smaller than y or the relative difference between x and y is smaller than the configured epsilon. The function cannot be used to compare values smaller than approximately 2.22e-16. For matrices, the function is evaluated element wise. Strings are compared by their numerical value. ## Syntax ```js math.smallerEq(x, y) ``` ### Parameters Parameter | Type | Description --------- | ---- | ----------- `x` | number | BigNumber | Fraction | boolean | Unit | string | Array | Matrix | First value to compare `y` | number | BigNumber | Fraction | boolean | Unit | string | Array | Matrix | Second value to compare ### Returns Type | Description ---- | ----------- boolean | Array | Matrix | Returns true when the x is smaller than y, else returns false ### Throws Type | Description ---- | ----------- ## Examples ```js math.smaller(1 + 2, 3) // returns false math.smallerEq(1 + 2, 3) // returns true ``` ## See also [equal](equal.md), [unequal](unequal.md), [smaller](smaller.md), [larger](larger.md), [largerEq](largerEq.md), [compare](compare.md)
