Remove x number of decimals from a float value

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I am trying to implement a 100% math function ( avoid handle the float as a char array), that remove x number of decimals from the right to the float point.

Example:
Given x= 12345.6789 I call the function with (x,2) and the returned number is: x= 12345.67, for (x,4) returned value is x=12345

I was trying to implement this function using datatype casting, abs() and other functions from math.h library.

Thanks for any advice,
