Similar to Income, this class hardcodes the type of the transaction, but now it passes EXPENSE to the superclass. The difference is that it transforms the given amount to be negative. Therefore, no matter if the user sends a positive or a negative value, we will always store it as...
Float, or "floating point number" is a number, positive or negative, containing one or more decimals. Example Floats: x =1.10 y =1.0 z = -35.59 print(type(x)) print(type(y)) print(type(z)) Try it Yourself » Float can also be scientific numbers with an "e" to indicate the ...
To get a floating-point number from a string, use thefloatStrToFloatmethods. They accept a string that consists of digits, decimal separator, "+" or "-" symbols and mantissa (the "e" or "E" character followed by a positive or negative integer) and returns a floating-point number. If ...
MultiByteCharSetProber runs the text through the encoding-specific state machine, one byte at a time, to look for byte sequences that would indicate a conclusive positive or negative result. At the same time, MultiByteCharSetProber feeds the text to an encoding-specific distribution analyzer. ...
