abs(3f)
NAME
abs, iabs, dabs, cabs, zabs − Fortran absolute value
SYNTAX
integer i1, i2
real r1, r2
double precision dp1, dp2
complex cx1, cx2
double complex dx1, dx2
r2 = abs(r1)
i2 = iabs(i1)
i2 = abs(i1)
dp2 = dabs(dp1)
dp2 = abs(dp1)
cx2 = cabs(cx1)
cx2 = abs(cx1)
dx2 = zabs(dx1)
dx2 = abs(dx1)
DESCRIPTION
The abs function is the family of absolute value functions. The iabs function returns the integer absolute value of its integer argument. The dabs function returns the double-precision absolute value of its double-precision argument. The cabs function returns the complex absolute value of its complex argument. The zabs function returns the double-complex absolute value of its double-complex argument. The generic form abs returns the type of its argument.
