There is a restriction in C language while using the modulus operator. it can operator only on integers and cannot operate on floats or double. If anyone tries to use the modulus operator on floats then the compiler would display error message as ‘Illegal use of Floating Point’.

Let us see this with an example:

main () { float x=7,y=5; int z; z = x % y; printf( %d”, z)’; }

This above program would give error as ‘Illegal use of Floating Point’.

基本上是说 % (modulus) 必须用整数 (int).
这样行吗?

z = ((int)paid - (int)price)%(50);
