Read about return values of log10 function .

1st Parameter Type : double

Double-precision floating point (±1.7E±308, ~15 decimal digits)

1st Parameter

The input value for which the base-10 logarithm is to be computed.

The log10function in C language Calculates the base-10 logarithm of the specified number.

The log10 function computes the common (base-10) logarithm of x. If x is positive, the result is the base-10 logarithm of x. If x is zero or negative, a domain error occurs, and errno is set to EDOM.

The log10function takes 1 parameter:

•
double `x`: The input value for which the base-10 logarithm is to be computed.

Computes the base-10 logarithm of the given input `x`. The function is defined for positive values of `x` and returns `-HUGE_VAL` for values less than or equal to 0. Returns the base-10 logarithm as a `double`.

The log10 function return value :

Returns the base-10 logarithm of x
If x is positive infinity, positive infinity is returned
If x is 0, negative infinity is returned and errno is set to ERANGE
For negative x (including negative infinity), a domain error occurs, and errno is set to EDOM

Output

This example demonstrates basic usage of log10 function to compute the base-10 logarithm of 100.
