NAME

log10, alog10, dlog10, clog10 − Fortran common logarithm intrinsic function

SYNOPSIS

real r1, r2
double precision dp1, dp2
complex cx1, cx2

r2 = alog10(r1)
r2 = log10(r1)

dp2 = dlog10(dp1)
dp2 = log10(dp1)

cx2 = clog10(cx1)
cx2 = log10(cx1)

DESCRIPTION

alog10 returns the real common logarithm of its real argument.  dlog10 returns the double-precision common logarithm of its double-precision argument.  clog10 returns the complex common logarithm of its complex argument.  The generic function log10 becomes a call to alog10, dlog10, or clog10 depending on the type of its argument.
