Rounding Floating Point Number To two Decimal Places in C and C++
How to round off a floating point value to two places. For example, 5.567 should become 5.57 and 5.534 should become 5.53
First Method:- Using Float precision
Time Complexity: O(1), as the execution time does not depend on the size of the input.
Space Complexity: O(1), as it only uses a fixed amount of memory to store a single float variable and does not allocate any dynamic memory.
Second Method: Using integer typecast If we are in Function then how return two decimal point value
The round function only performs a few basic arithmetic operations, so its time complexity is constant or O(1).
The round function creates a single float variable named value, so its space complexity is constant or O(1).
Third Method: using sprintf() and sscanf()
