subtract numbers from character

[RebeccaJW]

Hello,

I am asked to subtract the numeric portion of a character variable using input(), substrn() or scan(). 

Thank you in advance for your help!

This is what the original character look like.This is the expected result.

Subtract them from what?

How do those align? How does 10.5[1] become 15.7 or is that just a generic example?

If you're just trying to remove the [1] section, use SCAN and INPUT.

num_var = input(scan(char_var, 1, "[]"), best32.);
