将科学计数法字符串中的数字转换为使用有限的类C库浮动

Question

I'm writing a program in CAPL (which is based on C and minus some concepts) to convert a string containing a number displayed in scientific notation to a float (doesn't strictly need to be a float but I think its an appropriate type for this). For example:

-7.68000000E-06 should be converted to -0.00000768

I've done some looking around for this and atof() comes up a lot but this is not supported in CAPL so I cannot use that.

A list of the other C concepts not supported in CAPL:

Update: Thanks everyone for the help. M. Spiller's answer proved to be the easiest solution. I have accepted this answer.
