FLOATCALC$
Purpose Function for calculation with float numbers.
Syntax FLOATCALC$(,,[,])
Chapter —Program Instructions
is the first operand.
is the operator (+, -, *, or /).
is the second operand.
is, optionally, the precision in decimals (default 10).
Remarks Operands are float numbers, that is, a string of digits with a decimal point
to separate decimals from integers. Operands can also contain leading plus
(+), minus (-), and space characters. Space characters are ignored, whereas
the usual mathematical rules apply to plus and minus signs. All other
characters (or plus, minus, and space characters in other positions than
leading) generate errors.
Note the mathematical rules:
- - yields +
- + yields -
+ - yields -
+ + yields +
The following arithmetic operators are allowed:
+ addition ASCII 043 dec
- subtraction ASCII 045 dec
* multiplication ASCII 042 dec
/ division ASCII 047 dec
Any other type of operators or other characters will generate an error.
The precision parameter optionally specifies the number of decimals in
the result of the calculation. The result will be truncated accordingly. For
example, if the number of decimals is specified as 5, the result 5.76123999
will be presented as 5.76123. The result of a FLOATCALC$ function can
be formatted using a FORMAT$ function.
Examples Addition:
A$ = "234.9"
B$ = "1001"
PRINT FLOATCALC$ (A$,"+",B$,5)
yields:
1235.90000
Subtraction:
A$ = "234.9"
C% = 2
PRINT FLOATCALC$ (A$,"-",100.013,C%)
134.88
yields:
