sqrt(3f)
NAME
sqrt, dsqrt, csqrt − Fortran square root intrinsic function
SYNTAX
real r1, r2
double precision dp1, dp2
complex cx1, cx2
r2 = sqrt(r1)
dp2 = dsqrt(dp1)
dp2 = sqrt(dp1)
cx2 = csqrt(cx1)
cx2 = sqrt(cx1)
DESCRIPTION
The sqrt function returns the real square root of its real argument. The dsqrt function returns the double-precision square root of its double-precision argument. The csqrt returns the complex square root of its complex argument. The sqrt function, the generic form, will become dsqrt or csqrt as required by its argument type.
