[−][src]Function qt_core::q_float_distance_2_double
pub unsafe fn q_float_distance_2_double(a: c_double, b: c_double) -> u64
Returns the number of representable floating-point numbers between a and b.
Calls C++ function: quint64 qFloatDistance(double a, double b)
.
Returns the number of representable floating-point numbers between a and b.
This function serves the same purpose as qFloatDistance(float, float)
, but returns the distance between two double
numbers. Since the range is larger than for two float
numbers ([-DBL_MAX,DBL_MAX]
), the return type is quint64.
This function was introduced in Qt 5.2.
