1 absolute Value function abs (x) Cases: SQL query: ? 1 SELECT ABS ( -1), ABS (0), ABS (1) Execution results: 2 square root function sqrt (x) Cases: SQL query: ? 1 SELECT SQRT (4), SQRT (16)

Feel that some netizens always put forward some very basic questions, for example, there is no function to achieve such functions ah, what is the function of Ah, what the format is, and so on, but also feel their understanding of the lack of Oracle

To learn a small example today, use the C language to display a 0-360-degree cosine function cos (x) curve with "*" on the screen. Simulation Method: #include #include int main (void)... { Double i; int j,k; for (i=1.0; i>=-0.4; I-=0.1)

Mathematical functions are mainly used to deal with numerical data, the main mathematical functions are: absolute value function, trigonometric functions (including sine function, cosine function, tangent function, cotangent function), logarithmic

This article is not ready to introduce all of the Oracle functions, in the current situation, I do not have this time, need to learn too much, to spend most of the time on learning to use the technical aspects:), so if you are ready to learn all the
