Doubles may be used as inputs, outputs, and uniforms. The shading language supports various arithmetic and comparison operators on double-precision scalar, vector, and matrix types, and provides a set of built-in functions including: * square roots and inverse square roots; * fused floating-point multiply-add operations; * splitting a floating-point number into a significand and exponent (frexp), or building a floating-point number from a significand and exponent (ldexp); * absolute value, sign tests, various functions to round to an integer value, modulus, minimum, maximum, clamping, blending two values, step functions, and testing for infinity and NaN values; * packing and unpacking doubles into a pair of 32-bit unsigned integers; * matrix component-wise multiplication, and computation of outer products, transposes, determinants, and inverses; and * vector relational functions. Double-precision versions of angle, trigonometry, and exponential functions are not supported. Implicit conversions are supported from integer and single-precision floating-point values to doubles, and this extension uses the relaxed function overloading rules specified by the ARB_gpu_shader5 extension to resolve ambiguities. This extension provides API functions for specifying double-precision uniforms in the default uniform block, including functions similar to the uniform functions added by EXT_direct_state_access (if supported). This extension provides an "LF" suffix for specifying double-precision constants. Floating-point constants without a suffix in GLSL are treated as single-precision values for backward compatibility with versions not supporting doubles; similar constants are treated as double-precision values in the "C" programming language. This extension does not support interpolation of double-precision values; doubles used as fragment shader inputs must be qualified as "flat". Additionally, this extension does not allow vertex attributes with 64-bit components. That support is added separately by EXT_vertex_attrib_64bit.
