## Converting simulation time to and from string form.

These functions are copies of the functions with similar names (without the NED prefix) in the simulation kernel.
double | NEDStrToSimtime (const char *str)
double | NEDStrToSimtime0 (const char *&str)
char * | NEDSimtimeToStr (double t, char *dest=NULL)

## Function Documentation

char* NEDSimtimeToStr | ( | double | t,
|  | char * | dest = `NULL`
| ) |

| Converts simulation time (passed as double) into a string like "0.0120000 (12ms)". If no destination pointer is given, uses a static buffer.

double NEDStrToSimtime | ( | const char * | str | ) |

| Convert a string to double. The string should have a format similar to the one output by simtimeToStr() (like "1s 34ms"). Returns -1 if the whole string cannot be interpreted as time. Empty string (or only spaces+tabs) is also an error. E.g. strtoSimtime("3s 600ms x") will return -1.

double NEDStrToSimtime0 | ( | const char *& | str | ) |

Convert the beginning of a string to double.

Similar to strToSimtime(), only it processes the string as far as it can be interpreted as simulation time. It sets the pointer passed to the first character which cannot be interpreted as part of the time string, or to the terminating zero. Empty string is accepted as 0.0. E.g. strToSimtime0("3s 600ms x") will return 3.6 and the pointerstr will point to the character 'x'.
