| pe_unit_new | |
Creates a new unit of measure
PE_UNIT pe_unit_new (const char *name, double factor);
| name | Name of the new unit |
| factor | The ratio of meters/unit for linear units or radians/unit for angular units |
Defines a new unit of measure with the specified attributes
The value of the factor is either (a) number of meters per 1 unit for linear units or (b) number of radians per 1 unit for angular units.
x meters = factor * 1 unit, i.e., factor = meters / unit
1 unit = n meters, where n = factor
1 meter = n units , where n = 1 / factor
x radians = factor * 1 unit, i.e., factor = radians / unit
1 unit = n radians, where n = factor
1 radian = n units , where n = 1 / factor
On success, the new unit with the attributes equal to the corresponding arguments; on failure, a null pointer
PE_UNIT ft = pe_unit_new("ft",0.3048);
PE_UNIT dd = pe_unit_new("deg",PI/180);
