number

随机数

randomInt: (min?: number, max?: number): number

获取限定大小的随机整数

randomInt(5, 100); // 默认min = 0; max = 10;

量级转换

toThousands:(val: string | number, digit: number = 0): string

将数字转换为千位制转换，digit小数点精确到几位

toThousands(9999999); // '9,999,999'
toThousands(9999999.000, 3); // '9,999,999.000'

bitUpgrade: (n:number, opt: UpgradeOptions): string

比特转换

type UpgradeOptions = {
	decimal?: number, // 保留几位小数 默认俩位
	delimiter?: string, // 数字和单位之间的分隔符 默认为 无
}
bitUpgrade(1000); // '1.00KB'
bitUpgrade(1025, {delimiter: ' '}); // '1.00 KB'
bitUpgrade(999); // '999B'

bitRateUpgrade

比特率转换

bitRateUpgrade(1000);//'1000bps'
bitRateUpgrade(1025, {delimiter: ' '}); // '1.00 Kbps'

unitUpgrade:(num: number, options?: UnitUpgradeProps): number, string

单位进阶

UnitUpgradeProps = {
	type?: 'bit' | 'bitRate',
	decimal?: number, // 保留几位小数 默认俩位
}
unitUpgrade(1000); //(['1.00', 'KB']

toFixed: (num:number, fix?: number);

4舍5入，避免原生toFixed的银行家舍入法导致的问题

最值

max: (...args: number[]): number;

求最大值

max(3,4,9); // 9

min: (...args: number[]): number;

求最小值

min(3,4,9); // 3
