This function is an inbuilt PHP function which is being used from PHP 4 version.Syntaxmixed iconv_get_encoding($type = "all")ParameterThe iconv_get_encoding() function is used only single parameter $type.$type − The values of the optional type parameter can beallinput_encodingoutput_encodinginternal_encodingReturn ValueThe iconv_get_encoding() function returns the current value of the internal configuration variable if successful or it returns False on failure. If the type is not present or set to all,  then iconv_get_encoding() returns an array that stores all these variables.Example 1 Live Demo     Outputarray(3) {    ["input_encoding"]=>   ... Read More

In PHP, the bcsqrt() function is used to get the square root of an arbitrary precision number. It accepts the arbitrary precision number as a string and gives the square root of the number after scaling the result to the specified precision.Syntaxstring bcsqrt($num_string, $scale)ParametersThe bcsqrt() function accepts two different parameters: $num_string and $scale.$num_string − It represents the number whose square root to be evaluated. It is a string-type parameter.$scale − It indicates the number of digits that appear after the decimal point in the output.Return ValueThe bcsqrt() function returns the square root of the number as a string.Example 1OutputOutput without ...

In PHP, bcscale() function is used to set the default parameter for all bc math functions. This function sets the default scale parameter for all following calls to the bc math functions that do not explicitly specify a scale parameter.Syntaxint bcscale($scale)ParametersThe $bcscale() parameter accepts only a single parameter and it is the mandatory integer type parameter. This parameter shows the number of digits which come after the decimal. Its default value is 0.Return ValueThe $bcscale() function returns the old scale value.Example 1Output113.55960 113.5 113.55957Example 2Output113.55960 113.55 113.559

In PHP, bcpowmod() function is used to raise an arbitrary precision base number to another exponent number, reduced by a specified modulus. The bcpowmod() function accepts three arbitrary precision numbers as strings and it returns the base number raised to the exponent modulo number after scaling the result to the specified precision.SyntaxString bcpowmod($base, $exponent, $modulus, $scale)ParametersThe bcpowmod() function accepts four different parameters− $base, $exponent, $modulus and $scale.$base− It represents the left operand. It is a string type parameter.$exponent− It represents the right operand number which represents the exponent. It is a string type parameter.$modulus− The $modulus parameter accepts the operand ...

In PHP, bcdiv() math function is used to divide one arbitrary precision number from another number. The bcdiv() function takes two arbitrary precision numbers as strings and it gives the result as a division of two numbers after scaling the result to an identified precision. Or, we can say that the bcdiv() PHP function divides the dividend by the divisor.Syntaxstring bcdiv($num_string1, $num_string2, $scaleVal)ParametersThe bcmul() math function accepts three different parameters $num_string1, $num_string2 and $scaleVal.$num_string1 − It represents the dividend and it is the string type parameter.$num_string2 − It represents the divisor, it is the string type parameter.$scaleVal  − It is the optional ...

In PHP, bcmod() math function is used to calculate the modulus of an arbitrary precision number. The bcmod() function takes an arbitrary precision number as strings and it gives the result as a modulus of numbers after scaling the result to an identified precision. Or, we can say that it gets the remainder after dividing string_num1 by string_num2. Unless the string_num2 is 0, the result has the same sign as string_num1.Syntaxbcmod(string_$num1, string_$num2, [, int $scale=0])Or, bcmod(string $dividend, string $divisor[, int $scale=0])Note− The above syntax will get the remainder of dividing $string_num1 by $string_num2. Unless string_num2 is 0, the result has ... Read More

In PHP, bcmul() math function is used to multiply one arbitrary precision number with another number. The bcmul() function takes two arbitrary precision numbers as strings and it gives the result as the multiplication of two numbers after scaling the result to an identified precision.Syntaxstring bcmul( $num_string1, $num_string2, $scaleVal)ParametersThe bcmul() math function accepts three different parameters $num_string1, $num_string2 and $scaleVal.$num_string1 - It represents the left operand and it is the string type parameter.$num_string2 - It represents the right operand, it is the string type parameter.$scaleVal - This is the optional integer type parameter that is used to set the number of digits ...
