How to declare real constants? Please help

[260791]

How do I declare constants beginning with "zero" in Fortran to get the output beginning with zero ?

If I declare :

REAL, parameter :: tension = 0.025

I get the output:

2.500000E-02



Thanks in advance

Use a format statement

print '(F6.3)', tension

Excellent ! It works Thank you

And another problem that I have now is that:

E.g. for this calculation:

mddc = 0.3625 * ( tension / density ) ** 0.6
PRINT '(F6.3)', mddc

I'm getting: 0.001

while it should be 0.00069

and for others I'm getting 0.005, but should be 0.00471, so it rounds up the last digits.

What can I do, so that it will NOT round up the numbers at the end?



Thanks

Think you have to read up about format statements.

F means fixed format
6 is the number of digits in total including sign and decimal point
3 is the number of decimal places

It does round the answer up to the number of digits you specify. You probably want F10.5
