TSP (libtsp/ST) - STdecNfloat

## STdecNfloat

#### Routine

int STdecNfloat (const char String[], int Nmin, int Nmax, float Fval[], int *N)

#### Purpose

Decode float values (variable number)

#### Description

This routine decodes a string containing numeric data. Multiple data items data items in the string are separated by commas or white-space (as defined by the isspace routine). The decoded data is stored as float values. If the number of data values in the string is less than a given minimum number or a decoding error is detected, an error message is printed and an error indication is returned. A warning messages is printed if extra data follows the requested values (this data is ignored).

#### Parameters

<- int STdecNfloat
  Error status,

        0 - no error
        1 - error, too few values or data format error
        2 - warning, data values too large or too small

-> const char String[]
  Input string
-> int Nmin
  Minimum number of values to be read (may be zero)
-> int Nmax
  Maximum number of values to be read
<- float Fval[]
  Array of Nmax elements used to store the decoded values. Only the first N values are modified.
<- int *N
  Actual number of values decoded. In the case of an error, N indicates the number of values successfully decoded. In that case, N may be less than Nmin.
