Full Discussion: Generate Regex numeric range with specific sub-ranges

The fact you took your time to explain in detail how it works where even a 5 years old kid can understand is very much appreciated.

I've seen many smart users replying with solutions who don't fail to explain the logic ... in my view that is a useless answer since it doesn't help the requester to understand/ learn how it works.

All the best!!

glgetshaderprecisionformat

GLGETSHADERPRECISION(3G)					  [FIXME: manual]					  GLGETSHADERPRECISION(3G)

NAME

       glGetShaderPrecisionFormat - retrieve the range and precision for numeric formats supported by the shader compiler

C SPECIFICATION

       void glGetShaderPrecisionFormat(GLenum shaderType, GLenum precisionType, GLint *range, GLint *precision);

PARAMETERS

       shaderType
	   Specifies the type of shader whose precision to query.  shaderType must be GL_VERTEX_SHADER or GL_FRAGMENT_SHADER.

       precisionType
	   Specifies the numeric format whose precision and range to query.

       range
	   Specifies the address of array of two integers into which encodings of the implementation's numeric range are returned.

       precision
	   Specifies the address of an integer into which the numeric precision of the implementation is written.

DESCRIPTION

       glGetShaderPrecisionFormat retrieves the numeric range and precision for the implementation's representation of quantities in different
       numeric formats in specified shader type.  shaderType specifies the type of shader for which the numeric precision and range is to be
       retrieved and must be one of GL_VERTEX_SHADER or GL_FRAGMENT_SHADER.  precisionType specifies the numeric format to query and must be one
       of GL_LOW_FLOAT, GL_MEDIUM_FLOAT GL_HIGH_FLOAT, GL_LOW_INT, GL_MEDIUM_INT, or GL_HIGH_INT.

       range points to an array of two integers into which the format's numeric range will be returned. If min and max are the smallest values
       representable in the format, then the values returned are defined to be: range[0] = floor(log2(|min|)) and range[1] = floor(log2(|max|)).

       precision specifies the address of an integer into which will be written the log2 value of the number of bits of precision of the format.
       If the smallest representable value greater than 1 is 1 + eps, then the integer addressed by precision will contain floor(-log2(eps)).

ERRORS

       GL_INVALID_ENUM is generated if shaderType or precisionType is not an accepted value.
