converting numbers to strings & strings to numbers 1

[kknowle2]

I need to know how to convert character strings to numbers and also how to convert numbers to strings.
Can anyone help?

Dear Kknowle2

This answer was designed by Mr. Rafael Isassi who wrote this lines:

c Just write your number to a string, or read your number from a string,
C instead of to or from an I/O unit (the fortran I/O routines perform the
C conversion). Example:

C To convert to a string:
character*10 string, format
data format /'(F10.2)'/
a=3.1416
write(string,format)a
C now print your string...
print *,string

C To convert a string to a floating point number:
string='123456.789'
read(string,*)b
C now print your number...
print *,b

end

I hope this will be useful to you
Regards

Here's another example of what KKnowle2 showed you in his reply:
It's in Fortran90/95, however the Fortran77 code would be almost identical...
( (10) and ! used for comments are not F77 compatible )

Character(10) string
Real x, y
x = 53.65 ! assign an initial value to x, 53.65
Write( string, '(f10.2)' ) x ! writes 53.65 into the string
Read( string, '(f10.0)' ) y ! reads the value from string and assigns it to y
End ! note the f10.0 format is nice... you don't have
! to know in advance where the decimal pt lies.
