The remainder when 1.25 is divided by 0.5 is 0.25.

Whe I use a calculator to get the remainder of 1.25 divided by 0.5 the results is 2.5, can any one explain me this.

0.5 divides 1.25 to get 2.5. There is no remainder involved in this division, unless you are talking about floor division (//), where 1.25 // 0.5 = 2 ... 0.25.

I think you have done division (//) not remainder (%). now, 1.25÷0.5 = 125÷50 =2.5 thats the answer. but if you have to find remainder then, yes answer should be 0.25 .

its simple--> see 1.25//0.5=2 1.25%0.5 = 1.25-0.5*2 = 1.25-1 = 0.25 pure maths....dont get cofused 1.25/0.5 = (1 + 0.25) / 0.5 = (1 / /0.5) +(1%0.5) + (0.25 //0.5) + (0.25%0.5) [ 0.25 here is the remainder ; when you again devide it with 0.5 it results 0.5] = 2 +0+ 0+0.25/0.5(as remainder in 0.25%0 5 is not zero so we have to do division) =2+0.5 ##// REMEMBER // ## 3 OPERATORS--> (% ) GIVES ONLY REMAINDER (//) GIVES PURE DIVISION VALUE (5//2= 2) (/ ) GIVES ULTUMATE DIVISION (5/2=2.5)

Since 1.25 % 0.5 As we want to calculate remainder or Modulo-Operator.So, 0.5x2=1 2 which is the quotient 1.25-1= 0.5 which is remainder

@JEEVANANDHAMS---->> // is the pure division operator giving only integer value... 1 . 25 // 0 . 5 = 125//50=int(2 . 5)= 2 IF U DO 1 . 25 / 0 . 5 = 2 . 5
