Function std.math.exponential.log10
Calculate the base-10 logarithm of x.
real log10
(
real x
) pure nothrow @nogc @safe;
double log10
(
double x
) pure nothrow @nogc @safe;
float log10
(
float x
) pure nothrow @nogc @safe;
x | log10(x) | divide by 0? | invalid? |
---|---|---|---|
±0.0 | -∞ | yes | no |
<0.0 | NAN | no | yes |
+∞ | +∞ | no | no |
Example

assert(fabs(log10(1000.0L) - 3) < .000001);
