How to get floating point value?

Question

For eg,3.75 I want only 75 how can I get it

Answer 1

in c/c++:

double x = 3.75;
double y = x - trunc(x); // y will be 0.75

there are some other variants, like
double y = x - (int)x; // if x will be in range of int

modulus operator (%) may not be applied to floating point operands!

Answer 2

In c ,float cannot be modulo with int

Answer 3

To add to Seb TheS 's answer:

x = 3.75
y = x % 1 * 100

Now, y would be 75. Make sure to type it in a way that fits in your programming language of choice.

Answer 4

Alright, then it would be:

y = x % 1.0 * 100

Try that, I think it should work.

Answer 5

3.75 % 1 = 0.75

Answer 6

Python:
x = 3.75
y = x % 1

while y % 1:
y *= 10

C:
float x = 3.75;
float y = x % 1.0;

while (y % 1.0) {
y *= 10.0;
}

Use modf from the math.h (cmath for C++) header file:-
