Setting decimal precision in C
How to print floating point numbers with a specified precision? Rounding is not required. For example, 5.48958123 should be printed as 5.4895 if given precision is 4.
For example, below program sets the precision for 4 digits after the decimal point:
We can generalize above method using pow()
In C, there is a format specifier in C. To print 4 digits after dot, we can use 0.4f in printf(). Below is program to demonstrate the same.
