我使用类星体框架，并有一个显示值的q滑块。我希望小数位数限制为1。

在版本js中

:formatter="value => value.toLocaleString(undefined, {minimumFractionDigits: 1, maximumFractionDigits: 1})"

:formatter="(value) => value.toFixed(1)"
 
<q-item-label class="u-text-user-selected-value">
   {{ eco }}{{ unitSymbol }}
 </q-item-label>

<q-item class="q-item__select q-item__slider">
            <q-slider
              :key="timestampUpdateEco"
              v-model="modelEco"
              @change="(value) => setValueEco(value)"
              :min="minBoundary"
              :max="maxBoundary"
              :step="1"
              label
              color="red-9"
            />
          </q-item>

甚至试图改变它被赋予的值。

英寸ts

private get eco(): number {
    return Number(this.uxOneThermalModuleStore.heatingEco.toFixed(1));
  }

  private async setValueComfort(value: number) {
      if (value < this.minBoundary + diff) {
        value = this.minBoundary + diff;
        this.modelComfort = value;
      }
      await this.uxOneThermalModuleStore.setHeatingComfort(value);
    }
  }

但我还是得到了62.9999999这样的值
