CFloatEdit
Inherits from CEdit
The CFloatEdit class provides an edit control that automatically evaluates fractions & simple math expressions and converts them into their decimal equivalents. CFloatEdit is extremely simple to use; once you have used ClassWizard to create a CEdit member variable for one of your dialog controls, just edit the generated header code & replace CEdit with CFloatEdit in the instantiation code (you also have to include floatedit.h).
At runtime, the user enters text into the control and when the control loses focus (ie:
the user presses TAB), the text is evaluated & replaced with the decimal
equivalent. The following are examples of legal expressions:
5/32
3 5/32 This is
three and five thirty-seconds
1/2 + 1/4
3 * 4
1/4 / 1/32
5 - 1/32
1.25 + 3/5
3/5 * 1.75
The main restriction is that the operands and operators (+-*/) must be space separated. Also, integer and fractional parts must be space separated.
There is no need to call any member functions for this class, so I won't bother to
describe them here. If you feel the urge, however, explore them at will...
