Mathematics and formatting

Operations on values and their textual representations.

std::string snt::val::to_string(val::BaseValue::PointerType value, int precision = static_cast<int>(std::cout.precision()))

Format a VAL value.

Parameters:

• value – Value to format.

• precision – Number of significant digits.

Returns:

Formatted value.

std::string snt::val::to_string(const val::Array::ShapeType &shape)

Format an array shape.

Parameters:

shape – Dimensions of the array.

Returns:

Formatted shape.

val::BaseValue::PointerType snt::val::math::abs(val::BaseValue::PointerType a)
