Syntax
#include <math.h> double log10(double x);Description
log10 calculates the base 10 logarithm of x.
log10 returns the computed value. If x is negative, log10 sets errno to EDOM and may return the value -HUGE_VAL. If x is zero, log10 returns the value -HUGE_VAL, and may set errno to ERANGE.
This example calculates the base 10 logarithm of 1000.0.
#include <math.h>
int main(void)
{
double x = 1000.0,y;
y = log10(x);
printf("The base 10 logarithm of %lf is %lf\n", x, y);
return 0;
/****************************************************************************
The output should be:
The base 10 logarithm of 1000.000000 is 3.000000
