1.(int)变量名[强制类型转换] 该转换方式主要用于数字类型之间的转换,从int类型向long,float,double,decimal 类型转换可以使用隐式转换,但从long型到int 就需要使用显示转换,即使用该类型的转换方式否则产生编译错误。 该方式对于浮点数会无条件的舍去,会失去精确度 对于char类型的到int类型的转换,传回的值是ASCII...

the format used to format a number with PHP number_format() function. Three elements may be specified: "decimals", "decimalSeparator" and "thousandSeparator". They correspond to the number of digits after the decimal point, the character displayed as the decimal point and the thousands separator...
The old formatting algorithms would generate only a limited number of digits, then would fill the remaining decimal places with zero. They could usually generate strings that would round-trip back to the original floating point value, but weren't great if you wanted the exact value (or the cl...
