español(rtos number [mode [precision]])
Convert that real number to a string.
This function converts a real number to a string. The argument number is the real number you want to convert.
Mode and precision arguments are optional arguments. The mode (1 through 5) selects the format of the string:
| Mode | Meaning |
|---|---|
| 1 | Scientific |
| 2 | Decimal |
| 3 | Engineering |
| 4 | Architectural |
| 5 | Fractional |
The precision argument allows you to select the number of places after the decimal point. The range is 0 to 8.
Examples
| Code | Returns | Format |
|---|---|---|
| (rtos 15.35 1 4) | "1.5350E+001" | Scientific. |
| (rtos 15.35 2 4) | "15.3500" | Decimal. |
| (rtos 15.35 3 4) | "1'-3.3500" | Engineering. |
| (rtos 15.35 4 4) | "1'-3 3/8" | Architectural. |
| (rtos 15.35 5 4) | "15 3/8" | Fractional. |
NOTE When you leave them out, the mode and precision arguments read the settings of system variables LUNITS (default = decimal units) and LUPREC (default = 4 decimal places). Thus, to automatically use the current system settings, simply leave out mode and precision.
