usePrecision

v0.0.15testeddemo

Reactively set the decimal precision of a number.

Examples

const value = ref(3.14159);
const result = usePrecision(value, 2); // 3.14

const value = ref(3.14159);
const result = usePrecision(value, 2, { math: 'ceil' }); // 3.15

const value = ref(3.14159);
const digits = ref(2);
const result = usePrecision(value, digits); // reacts to value and digits
