NAME
REAL, FLOAT, SNGL - Converts to type real
SYNOPSISREAL ([A=]a [,[KIND=]kind])
FLOAT ([A=]a [,[KIND=]kind])
SNGL ([A=]a [,[KIND=]kind])
IMPLEMENTATION
UNICOS and UNICOS/mk systems
STANDARDS
Fortran 90
DESCRIPTION
REAL, FLOAT, and SNGL are elemental functions for the CF90 compiler.
arg can be of type complex, integer, or real.
These functions convert specified types to type real, such as a (or a
for complex arguments). r
Type conversion routines assign the appropriate type to Boolean
arguments without shifting or manipulating the bit patterns they
represent.
