[DUPLICATE] What is mean % define it

Answer 1

modulus operator:it returns the remainder in divisions.
5%3=2
3%5=3
2%2=0
6%5=1

Answer 2

1.25= .5*2(=1)+.25

hence,
1.25 divided by .5, quotient is 2 and .25 isn't divided by .5 so it is remainder.

above term is expressed by modulus sign (%),where % shows only remainder,not shows quotient.

it is expressed by
5%2 = 1
11%4 = 3
12%7 = 5
1.25%.5 = .25
