API Reference for the SFE_QUAD_Sensors_sprintf class

Helper methods to support printing of double and exponent-format data.

Helper Methods

Convert double to string (included because not all platforms support dtostrf correctly).

It is the calling method's responsibility to ensure buffer is large enough to contain the complete string.

char *_dtostrf(double value, char *buffer)

Parameter	Type	Description
`value`	`double`	The double to be converted to string
`buffer`	`char *`	A pointer to a char array to hold the text
return value	`char *`	A pointer to the char after the final one printed

Convert double to ASCII text using exponent format.

It is the calling method's responsibility to ensure buffer is large enough to contain the complete string.

char *_etoa(double value, char *buffer)

Parameter	Type	Description
`value`	`double`	The double to be converted to string
`buffer`	`char *`	A pointer to a char array to hold the text
return value	`char *`	A pointer to the char after the final one printed

Convert exponent-format string to double.

bool expStrToDouble(const char *str, double *value)

Parameter	Type	Description
`str`	`const char *`	A pointer to the string to be converted
`value`	`double *`	A pointer to the double which will hold the result
return value	`bool`	`true` if the conversion was successful, `false` otherwise

Set the precision (number of decimal places) to be used by _dtostrf and _etoa.

Set this before calling mySensors.detectSensors();:

void setPrecision(unsigned char prec)

Parameter	Type	Description
`prec`	`unsigned char`	The precision

Returns the current precision.

unsigned char getPrecision(void)

Parameter	Type	Description
return value	`unsigned char`	The precision

Parameter	Type	Description
`_prec`	`unsigned char`	The precision (number of decimal places) to be printed
